A German rapper turned Islamic State terrorist has released a propaganda video where he calls on jihadist sleeper cells in Europe to carry out terrorist attacks.

Denis Cuspert, 39, dubbed the 'Goebbels of ISIS', sings about planning attacks in Britain, Germany and France, rapping 'We want your blood'.

This follows reports that British police have raised security levels ahead of several World War I commemorative events taking place next week.

Anzac Day, which takes place on April 25, honours Australian and New Zealand soldiers who have died in war, originally observed in memory of troops who fought at Gallipoli in 1915.

'We already have protective security plans in place for major Anzac events in the UK but as a sensible precaution all forces have been asked to review security arrangements at related events,' a Scotland Yard spokeman told the Sunday Times.

The propaganda production made by the 39-year-old, who now calls himself Abu Talha al-Amani, is filled with horrific footage of prisoners being beheaded and Jordanian pilot Moath al-Kasasbeh being burned alive.

In the slick three-minute video, he sings: ‘In France deeds were done, in Germany the sleepers are waiting. We want your blood.

‘Even if you’re in Europe, wage your jihad. Allah will reward you, put an end to the filthy ones. Oh Allah destroy them.’

German rapper turned Islamic State terrorist Denis Cuspert has released a music video threatening his home nation with a Charlie Hebdo-like atrocity

The video contains footage of passages from the Koran such as ‘kill the polytheists wherever you find them’ being highlighted, along with images of Western soldiers being treated in hospital and staged footage of bombs being assembled and guns being prepped.

NUMBER OF BRITISH ISIS FIGHTERS DOUBLE PREVIOUS ESTIMATES The number of Britons who have travelled to Iraq and Syria to join ISIS is twice than what has previously been reported. It is now thought that 1,600 Brits have joined ISIS, foreign intelligence officials told the Sunday Times. 'We believe that 1,600 is a very conservative estimate and we're seeing at least about five people leaving the UK for Syria anbd Iraq every week - and that's not to count the ones we don't know about,' an intelligence official said. According to the newspaper, about 500 have returned to the UK after heading to the Islamic State. Advertisement

News clips from last year’s Paris attacks carried out by Saïd and Chérif Kouachi – who murdered Charlie Hebdo staff members - and Amedy Coulibaly, who gunned down shoppers at a Jewish supermarket, also accompanie the singing.

Cuspert had been a relatively successful rapper under the name Deso Dogg before trading in his faux-gangster lifestyle to wage jihad on behalf of the Islamic State.

In February it was revealed that the militant - who has starred in several grisly beheading videos for the Islamic State - was being spied on for the FBI by a Syrian woman he thought was his wife.

The spy transmitted critical information about the rapper and his ISIS colleagues before escaping to Turkey - where she was arrested and then turned over to the US, according to the German newspaper Bild.

The paper said German and American intelligence sources confirmed the existence of the operation, Fox News reports.

The unidentified woman fled Syria after her handlers told her it was no longer safe to continue the mission as militants had began to hunt and flush out infiltrators. She is now thought to be in the US.

German newspaper Bild believe Cuspert may have been targeted for the operation because of his womanising past.

In Germany he fathered three children by three different women, including one who he dumped just before embarking on his career as an ISIS poster boy. Cuspert arrived in Syria in 2013 from a so-called German jihadi colony in Egypt.

In February the US added rapper Cuspert to its list of 'global terrorists' - freezing all his assets under US control and prohibiting any transactions with him in the future.

The State Department said: ' Cuspert is emblematic of the type of foreign recruit ISIL seeks for its ranks -– individuals who have engaged in criminal activity in their home countries who then travel to Iraq and Syria to commit far worse crimes against the people of those countries.'

Last November, Cuspert was compared to Nazi Minister for Propaganda Joseph Goebbels for his ability to appeal to young, disillusioned people in Europe while providing an alternative ideology.

He spent several years as a major player in the Berlin hip hop scene under the name 'Deso Dogg' before embracing radical Islam.

He has been known to oversee the group's sophisticated media operation and is reportedly using British fighters in an attempt to attract even more of their countrymen to the war-torn region.
