A memorial wreath in his hand, Jeremy Corbyn stands feet from the graves of terror leaders linked to the Munich Massacre.

The picture was among a number taken during a service to honour Palestinian 'martyrs'.

Buried in the cemetery in Tunisia are members of Black September, the terror group which massacred 11 Israeli athletes at the 1972 Olympics.

Last night sources close to Mr Corbyn insisted he was at the service in 2014 to commemorate 47 Palestinians killed in an Israeli air strike on a Tunisian PLO base in 1985.

But on a visit to the cemetery this week, the Daily Mail discovered that the monument to the air strike victims is 15 yards from where Mr Corbyn is pictured – and in a different part of the complex.

Instead he was in front of a plaque that lies beside the graves of Black September members.

The plaque honours three dead men: Salah Khalaf, who founded Black September; his key aide Fakhri al-Omari; and Hayel Abdel-Hamid, PLO chief of security.

Adjacent to their graves is that of Bseiso. All were assassinated either by the Israeli secret service Mossad or rival Palestinian factions.

With his party engulfed in a row over anti-Semitism, the pictures give Mr Corbyn fresh questions to answer about his alleged sympathy for extremists.

'It beggars belief that anyone would wish to honour the terrorists behind the brutal massacre of 11 Israeli athletes at Munich,' said Jennifer Gerber, director of Labour Friends of Israel.

'However, it is sadly utterly unsurprising that Jeremy Corbyn appears to have done so. Others will rightly regard it is as totally sickening.'

A Labour ex-minister took out a full-page advert in a Jewish newspaper to lambast Mr Corbyn's response to the anti-Semitism crisis. Jim Murphy said it had been 'intellectually arrogant, emotionally inept and politically maladroit';

The Board of Deputies of British Jews warned Mr Corbyn to 'come out of hiding' and said the anti-Semitism crisis would not go away.

Mr Corbyn recorded his visit to the Tunisian cemetery – a year before he became Labour leader – in an article for the communist newspaper, the Morning Star.

He said wreaths were laid to mark the 1985 bombing but also 'on the graves of others killed by Mossad agents'.

TERROR TRAIL THAT STARTED AT OLYMPICS Sept 5, 1972 Eight Palestinian terrorists from the Black September group storm the Munich apartments where Israeli athletes are sleeping, killing two and taking nine hostage. File photo shows a member of the Palestinian terrorist group who seized members of the Israeli Olympic team at their quarters at the Munich Olympic Village on September 5, 1972 When the terrorists and hostages were taken by helicopter to a military airport, German sharpshooters opened fire, killing three terrorists. A gun battle claimed the lives of all nine hostages and two terrorists. The remains of the helicopter which was used by Arab guerillas to escape from the Olympic village with 11 Israeli hostages. The helicopter was destroyed in a gun battle with German police Daily Mail's coverage of the Munich Massacre a day after the helicopter was shot down, which resulted in five terrorists and all eleven athletes being killed Oct 1, 1985 Israeli warplanes bomb the PLO headquarters in Hammam Chott, near Tunis, killing 47. Jan 15, 1991 PLO second-in-command Salah Khalaf, his adviser Fakhri al-Omari, and PLO security chief Hayel Abdel-Hamid are shot to death at Abdel-Hamid's home in Tunis. Jun 8, 1992 Atef Bseiso, the PLO's head of intelligence, is shot in Paris. It was reported he was killed because he helped to plan the Munich Massacre. Sep 30, 2014 Jeremy Corbyn attends a conference on the future of Palestine in Tunisia. It is also attended by Hamas. Oct 1, 2014 Mr Corbyn visits the Cemetery of the Martyrs of Palestine, on the outskirts of Tunis. In an article for the Morning Star about the visit, he writes: 'Wreaths were laid at the graves of those who died on that day (at Hammam Chott) and on the graves of others killed by Mossad agents in Paris in 1991.' May 28, 2017 The Sunday Times reports that Mr Corbyn had attended a wreath-laying ceremony at Bseiso's grave. Mr Corbyn denies this. Advertisement

He wrote: 'After wreaths were laid at the graves of those who died on that day and on the graves of others killed by Mossad agents in Paris in 1991, we moved to the poignant statue in the main avenue of the coastal town of Ben Arous, which was festooned with Palestinian and Tunisian flags.'

There appears to be no record of Mossad having carried out an assassination in Paris in 1991. However, Khalaf, Abdul-Hamid and al-Omari were assassinated that year. Mossad is accused of killing Bseiso in Paris in 1992.

Controversy over Mr Corbyn's visit became an issue during last year's general election.

He insisted he was not honouring Bseiso, adding: 'I was in Tunisia at a Palestinian conference and I spoke at that Palestinian conference and I laid a wreath to all those that had died in the air attack that took place on Tunis, on the headquarters of the Palestinian organisations there.

'And I was accompanied by very many other people who were at a conference searching for peace. The only way we achieve peace is by bringing people together and talking to them.'

Atef Bsesio (left) was the head of intelligence for the Palestine Liberation Organisation before his assassination outside a Paris hotel in 1992. In the years after his death, it was widely reported that he was killed because he helped to plan the Munich Massacre in 1972. On the night of his death, Bseiso returned from a late dinner with two friends to his luxury hotel in the French capital where he had registered under an assumed name. Lying in wait were two assassins, who fired three bullets into his head on a dark street. Hayel Abdel-Hamid (right) was chief of security of the Palestine Liberation Organisation. He was a close adviser to Salah Khalaf, and the pair were killed in an attack in Abdel-Hamid’s home in Tunis in 1991

Salah Khalaf (left) is widely believed to have masterminded the Munich Massacre. He created the Black September terror group which carried out the 1972 attack. Khalaf, better known by the nom de guerre Abu Iyad, went on to become Yasser Arafat’s second-in-command in the PLO. In January 1991, he was gunned down in the Tunisian capital of Tunis. Fakhri Al-Omari (right) was a senior member of Black September and was also implicated in the Munich Massacre. He was a close adviser to Khalaf and was killed in the same attack in Tunis in 1991

However, the pictures obtained by the Mail – and posted on the Facebook page of the Palestinian embassy in Tunisia – directly place Mr Corbyn by the graves of Bseiso and the Black September leaders.

He is seen standing under a distinctive red canopy with a corrugated steel roof. This canopy runs alongside the graves of the Munich-linked men.

Mr Corbyn is clearly pictured holding a wreath and seemingly praying by the distinctive plaque that honours Khalaf, Abdel-Hamid and al-Omari.

Their graves are apart from the 60 or so others in the cemetery and the plaque honouring the victims of the 1985 Israeli air strike.

The Corbyn source maintained that the service attended by the Labour leader was 'a Palestinian commemoration for those killed in the bombing in Tunis', even when presented with the photographs showing him in a different area of the cemetery.

The source insisted that the pictures did not contradict Mr Corbyn's statements. And the insider said the picture showing Mr Corbyn apparently joining in a prayer was simply of him 'copying the others out of respect'.

However, Gideon Falter, of the Campaign Against Anti-Semitism, said: 'A responsible politician would not have gone anywhere near that ceremony, but Mr Corbyn is not a responsible politician.

Given Mr Corbyn's history of defending, honouring and befriending anti-Semites, including genocidal anti-Semitic terrorists, this latest revelation adds to the deeply disturbing evidence that the leader of the opposition is a longstanding ally of those who wish us great harm.'

Mr Corbyn's remark comparing the Israelis with Nazis came in video from an event in 2013. It is controversial because the globally-accepted definition of anti-Semitism says it is anti-Semitic to compare the actions of the Israeli government with those of the Nazis.

Corbyn in fresh anti-Semitism storm as 2013 video emerges of him comparing the Israeli occupation of the West Bank to the Nazi takeover of Europe

By Daniel Martin and Kate Ferguson for MailOnline

Jeremy Corbyn was today accused of making a direct comparison between the Israeli occupation of the West Bank and the Nazi takeover of Europe.

A video has surfaced of him making the ‘appalling’ comment at an event in 2013, when he was still a backbencher.

The statement appears to flout the globally-accepted definition of anti-Semitism which says it is anti-Semitic to compare the Israeli government with the Nazis.

But Labour said Mr Corbyn was referring to all occupations in the Second World War, not just that of Adolf Hitler’s regime.

The Labour leader is facing mounting pressure to come back from his summer holiday to get a grip on the scandal tearing his party apart.

The Board of Deputies of British Jews said Mr Corbyn must stop being 'invisible' and 'come out of hiding' and get back to Westminster.

While ex Scottish Labour leader Jim Murphy took out a full page advert in a Jewish newspaper apologising for the scandal and laying the blame with the Labour leader.

It comes a week after Mr Corbyn was forced to apologise after being exposed for appearing at an event in 2010 where other speakers compared Israel to the Nazis.

What is the timeline of anti-Semitic scandals which have erupted under Jeremy Corbyn's leadership? Jeremy Corbyn (pictured) has been accused of failing to tackle the racism among his supporters The anti-Semitism scandal has dogged Labour since Jeremy Corbyn was elected leader in 2015. Here is a timeline of the controversies: April 2016: Labour MP Naz Shah is suspended for anti-Semitic posts - including one in which she appeared to endorse calls for Israelis to be deported to the US. She apologised and was given a formal warning. Ken Livingstone goes on the radio to defend Ms Shah - but sparks fresh controversy by claiming that Hitler supported Zionism. He is suspended by Labour but refuses to apologise and has repeated the claim many times. He eventually quits Labour two years later, saying his suspension has become a distraction. June 2016: A two-month inquiry by civil liberties campaigner Shami Chakrabarti finds that Labour is not overrun by anti-Semitism. But the launch is overshadowed when Jewish Labour MP Ruth Smeeth flees it in tears after being accused by Corbyn supporter Marc Wadsworth of colluding with the press. Critics accuse the report of being a whitewash and Ms Chakrabarti is widely criticised for accepting a peerage from Jeremy Corbyn shortly afterwards. October 2016: The Home Affairs Select Committee says Labour is guilty of incompetence over its handling of anti-Semitism and of creating a safe space for people with 'vile attitudes towards Jewish people'. March 2018: It is revealed that Jeremy Corbyn defended an artist who painted an anti-Semitic mural and said the offensive art should be removed. He apologises saying he did not properly look at the picture before he made the post. Jewish leaders take the unprecedented step of holding a demonstration outside Parliament protesting Mr Corbyn's failure to tackle anti-Semitism. Several Labour MPs address the crowds. April 2018: Marc Wadsworth is expelled from Labour after being accused of anti-Semitism. Meanwhile, Labour Jewish MPs tell of the anti-Semitic abuse they have suffered in a powerful parliamentary debate - and round on their leader for failing to tackle it. July 2018: The Labour leadership sparks fresh anger by failing to fully adopt the International Holocaust Remembrance Alliance's definition of anti-Semitism Peter Willsman, a strong ally of Jeremy Corbyn, is secretly taped ranting that 'Jewish Trump fanatics' invented the anti-Semitism storm engulfing Labour. In an angry diatribe at a meeting of Labour's ruling executive committee, he said he was 'amazed' there was evidence party members hated Jews. He claimed 'some of these people in the Jewish community support Trump – they are Trump fanatics' before shouting: 'So I am not going to be lectured to by Trump fanatics making up duff information without any evidence at all.' August 2018: Jeremy Corbyn issues a video insisting he is committed to tackling the racism - but it is panned by Jewish leaders. Corbynistas mount a social media campaign to get deputy Labour leader Tom Watson to quit after he criticises the party's handling of anti-Semitism. The Daily Mail exclusively publishes photos of Jeremy Corbyn holding a wreath at a ceremony where a terrorist linked to the Munich massacre was honoured. The Labour leader insists he was there to honour others killed - but faces fresh calls to quit over the scandal. Advertisement

Labour Friends of Israel tore into Mr Corbyn over the remark, saying: ‘The Labour party's once proud record on fighting racism and the protection of British Jews from anti-Semitism is being sacrificed to protect Jeremy Corbyn's reputation.’

The video was posted on the Twitter account of The Golem, who collates examples of anti-Semitism.

Earlier this week the same account published a 2011 video of Mr Corbyn apparently questioning Israel’s very right to exist.

In an interview with Iranian state TV, the then backbench MP said that the view that Israel had a right to exist was an example of ‘bias’ at the BBC.

This appears to contravene the International Holocaust Remembrance Alliance definition which states it is anti-Semitic to ‘deny the Jewish people their right to self-determination’.

The latest video shows Mr Corbyn making a speech at an event hosted by the Palestinian Return Centre.

He said: ‘The West Bank is under occupation of the very sort that is recognisable by many people in Europe who suffered occupation during the Second World War with the endless roadblocks, imprisonment, irrational behaviour by the military and the police.’

Last night Jennifer Gerber, director of Labour Friends of Israel, said: ‘Earlier this week, we discovered that Jeremy Corbyn engaged in wild conspiracy theories questioning Israel's right to exist.

‘Today, it is revealed he drew comparisons between conditions in the West Bank and the Nazi occupation of Europe.

‘It is increasingly clear that his opposition to adopting the IHRA definition in full appears to be overwhelmingly driven by his own appalling past statements.

‘The Labour party's once proud record on fighting racism and the protection of British Jews from anti-Semitism is being sacrificed to protect Jeremy Corbyn's reputation.’

It is not the first time the Labour leader has been accused of having compared the actions of the Israeli government with the Nazi regime.

In a rally in 2010 he said the siege of Gaza had lasted longer than those of Leningrad and Stalingrad.

A Labour spokeswoman said: ‘Jeremy was describing conditions of conditions of occupations in World War Two in Europe, of which there are multiple examples, not comparing the Israeli state to Nazis.’

It comes as Mr Murphy has today taken out a full page advert in a Jewish newspaper apologising for the anti-Semitism scandal.

He said he took the dramatic step of paying for the slot in the Jewish Telegraph because he could not stand silent as his party 'turned its back' on Jews.

The ex Cabinet minister launched a blistering attack on the Labour leader in the advert, accusing him of not doing 'nearly enough' to kick anti-Semites out of the party.

The astonishing attack comes as Jewish leaders furiously demanded that Mr Corbyn 'come out of hiding' from his holiday by the seaside and tackle the crisis.

In the advert, Mr Murphy branded Mr Corbyn and his allies 'intellectually arrogant, and emotionally inept' and said they have 'deliberately turned their back on British Jewry'.

He added: 'Today there's a small, but growing minority of anti-Semitic conspiracy theorists amongst the membership of the Labour Party.

'Jeremy Corbyn is not doing nearly enough to throw out the anti-Semites found within grassroots and online Labour.'

He laid the lame for the crisis squarely at the feet of the Labour leader and his supporters.

Mr Murphy, who lost his seat in 2015, said: 'No party leader has the right to hatter the relationship between British labour and British Jewry.

'The Jewish community and everyone else who is offended by Labour's stance are being asked to accept quarter-baked platitudinous Labour apologies for the "upset that has been caused".

'Instead what's needed urgently is Labour action against the sickening anti-Jewish racism that is the actual cause of the offence in the first place.'

Meanwhile, the Board of Deputies of British Jews president Marie van der Zyl warned the Labour leader 'you cannot lead through invisibility' and said that he must come back form holiday to get a grip on the crisis.

Writing in Jewish News, she said: 'He is clearly just hoping it will go away. I've got some bad news for him - unless he does what he needs to do, it won't.'

She added: 'I call on Jeremy Corbyn to come out of hiding and do the right thing.'

Why is Labour's new code of conduct on anti-Semitism so controversial? The Labour anti-Semitism row erupted again after the party leadership refused to fully adopt the International Holocaust Remembrance Alliance's (IHRA) definition. The party's code explicitly endorses the IHRA definition, but it omits four examples from the IHRA list: - Accusing Jewish people of being more loyal to Israel than their home country; - Claiming that Israel's existence as a state is a racist endeavour; - Requiring higher standards of behaviour from Israel than other nations; and - Comparing contemporary Israeli policies to those of the Nazis. Labour insisted that while the examples are not reproduced word-for-word, they are covered in the new code. But critics say the decision allows anti-Semitism to continue to fester. Advertisement

The Labour leader has been accused of purposely ignoring the racism which festers among some of his supporters.

While Labour MP Dame Margaret Hodge - who lost family members in the holocaust - says Mr Corbyn and his allies are using the row to try to purge the party of his moderate critics

It emerged yesterday that Mr Corbyn has been given a month to back down over the anti-Semitism row or face losing the backing of his powerful allies in Momentum.

The grassroots organisation helped install and keep Mr Corbyn in power.

The Labour leader has rebuffed demands by Jewish leaders and many of his own MPs to fully adopt the international definition of anti-Semitism - a move they insist is crucial if the party is to finally get on top of the scandal.

The party has adopted some of the International Holocaust Remembrance Alliance's definition.

But crucially it has not included several of the examples they use to illustrate it - including that Israel's existence as a state is a racist endeavor.

Mr Corbyn has now been told by Momentum he must formally sign up to the definition at a crunch party meeting in early September, the Politico website reports.

While the GMB trade union - one of the UK's biggest trade unions and a major force in Labour - has also come put to publicly demand the same.

If he refuses they could pull support for him - triggering what could be the biggest crisis in his leadership since the failed coup against him in the summer of 2016.
