Poland’s foreign ministry has summoned the United States' ambassador in Warsaw demanded an apology, after the head of the FBI suggested that Poles bore some responsibility for the Holocaust.

FBI director James Comey suggested in a Washington Post article that some Poles were accomplices to the murders of World War Two, stating that,

“In their minds, the murderers and accomplices of Germany, and Poland, and Hungary, and so many, many other places didn’t do something evil. They convinced themselves it was the right thing to do, the thing they had to do.”

“That’s what people do,” continued Mr Comey. “And that should truly frighten us.”

His comments angered Poland with Prime Minister Ewa Kopacz saying it was “unacceptable”.

“To those who are incapable of presenting the historic truth in an honest way, I want to say that Poland was not a perpetrator but a victim of world war two,” Ms Kopacz said. “I would expect full historical knowledge from officials who speak on the matter.”

As many as 700 migrants are feared to have died as the vessel they were travelling in sank off the Libyan coast on Sunday.

Italy’s interior ministry reported that only 28 survivors have been rescued, in one of the worst maritime disasters of its kind in the Mediterranean.  The vessel, which was reportedly carrying up to 900 migrants attempting to reach Europe, sank after the refugees on board attempted to catch the attention of a Portuguese merchant ship to rescue them. 

“They wanted to be rescued,” said Barbara Molinario, a spokeswoman for UNHCR. “They saw another ship. They were trying to make themselves known to it,” she added.

The disaster means that some 1,500 migrants have died so far in the Mediterranean in 2015 alone – a figure 30 times higher than in 2014. As many as 400 people drowned to death in a similar incident last week.

"Gangs of criminals are putting people on a boat, sometimes even at gunpoint… They're putting them on the road to death, really, and nothing else," said Mr Muscat.

He told CNN that it was "genocide - nothing less than genocide, really".
