Turkish leader Tayyip Erdogan has issued a chilling warning that Europeans 'will not walk safely on the streets' as tensions between Ankara and the EU escalated further today.

Erdogan has been locked in a row with Germany and Holland after his officials were barred from drumming up support on the continent for an April referendum on boosting his powers.

During a speech in Ankara, the president said: 'If you continue to behave like this, tomorrow in no part of the world, no European, no Westerner will be able to take steps on the street safely and peacefully.'

Erdogan did not expand on what he meant by his comments but appeared to imply that Europeans risked receiving the same treatment that, he says, is endured by Turks and Muslims in Europe.

Relations between Turkey and Europe have been severely strained since Turkish ministers were thwarted from campaigning on the continent for a 'yes' vote in next month's referendum on expanding Erdogan's powers.

Ankara has said such behaviour was reminiscent of Nazi Germany and also raised alarm over what it sees as rising racism and Islamophobia on the continent.

Erdogan warned Europe that Turkey was 'not a country to push, to prod, to play with its honour, to shove its ministers out of the door, drag its citizens on the floor.'

He said the world was watching Europe's actions 'very closely', adding: 'We as Turkey urge Europe to respect democracy, human rights, freedoms.'

His repeated comparisons with Nazi Germany have been strongly condemned by the European Union as well as Berlin and the Hague, precipitating a crisis that has raised doubts over the viability of Turkey's EU bid.

Tensions with Germany have been further damaged after Deniz Yucel, the Turkey correspondent of the German newspaper Die Welt, was jailed last month on terror charges. He is awaiting trial.

The president accused German consular officials of allowing Yucel to take refuge in the residence of the German consul in Istanbul for a month to evade arrest.

Erdogan again condemned German Chancellor Angela Merkel, whom he previously claimed is 'supporting terrorists', after she urged a Turkish-German journalist to be freed and gave her support to the Dutch during the height of the crisis over rallies.

'You say 'I am with the Netherlands'. Well, I am with my people,' Erdogan said.

Press defenders say that Turkey is holding 149 journalists in jail and EU leaders have repeatedly expressed alarm over freedom of expression in the country.

But Erdogan denied there was a single bona fide reporter in jail in the country.

'Everyone is there, from murderers to robbers, child abusers to fraudsters. In this list, only journalists are not present,' he said.

Referring to a list of Turkish journalists detained given to Turkish authorities, he said: 'Our friends looked at this and 144 are in jail for terror charges, the other four for common crimes.'

On April 16, Turks will decide whether to approve constitutional changes that would abolish the post of prime minister and could see Erdogan stay in power until 2029.

The government argues it will ensure stability in Turkey but critics argue it is regime-change and will lead to one-man rule.
