Hundreds of Iraqis returned home Thursday on an Iraqi Airways flight from Belarus, where thousands of migrants have camped on the Polish border for weeks hoping to enter the EU.

A total of 431 people were aboard the Boeing 747, said a spokesman for the government of the autonomous region of Kurdistan where many of the repatriated Iraqis came from.

Belarus and the European Union confirmed on Wednesday they were having talks on the repatriation of the migrants, who were stuck on the Belarus-Polish border. 

Belarus on Thursday said there were around 7,000 migrants in the country, with around 2,000 of them camped on the border with EU member Poland.

Thousands of mainly Middle Eastern migrants are camped around the border in what the West says is revenge for sanctions slapped on Belarusian strongman leader Alexander Lukashenko's regime after it suppressed protests last year.

"The European Union is creating a humanitarian corridor for 2,000 refugees who are in the camp. We are taking on the responsibility of -- as much as it is possible and if they wish -- returning the 5,000 others to their homes," Lukashenko's spokeswoman Natalya Eismont said. 

She said German Chancellor Angela Merkel would negotiate with the EU on creating the humanitarian corridor to Germany.

Berlin denied any agreement with Lukashenko on a possible humanitarian corridor.

"Germany did not agree to that. It is a European problem and Germany is not going it alone," a government source told AFP.

Speaking separately in Warsaw, German Interior Minister Horst Seehofer also firmly put down any rumours that Germany would take in the 2,000 migrants.

He said he "immediately contacted" Merkel when he heard the claim, "and received the clear information that this was fake news".

Lukashenko has dismissed the accusation that he engineered the crisis and criticised the EU for not taking in the migrants.

This week he spoke twice by telephone with Merkel in his first call with a Western leader since last year.
