Germany is expecting a record 800,000 asylum seekers to arrive this year, including a large number who are fleeing the conflict in Syria.

German Chancellor Angela Merkel warned on Tuesday that creating a “safe zone” for refugees in northern Syria could put them at risk of being massacred, starkly distancing her country from a Turkish proposal.

France said on Monday it would discuss with its partners in the coming days the suggestion by Turkey and members of the Syrian opposition that a “no-fly zone” could be created in northern Syria.

Speaking to lawmakers from her party in Berlin, Merkel expressed concern about the dangers of trying to create such a buffer zone.

“If we were not able to guarantee security, then a situation would arise that would be even worse than Srebrenica,” Merkel said, according to a number of people present in the meeting, referring to the slaughter of some 8,000 Muslim men and boys by Bosnian Serb forces in 1995.

There was concern that Islamic State could overrun such a security zone.

Struggling with more than 1.8 million Syrian refugees, Turkey has long campaigned for a “no-fly zone” in northern Syria to keep Islamic State of Iraq and Syria (ISIS) and Kurdish militants from its border and help stem the tide of displaced civilians trying to cross.
