Syria’s cross-border firing on Syrian refugees in Turkey this week is increasing pressure on the Turkish government to take military action in response, but a former Turkish foreign minister says that may only make a bad situation worse.

An United Nations deadline for the Syrian regime and its opposition to halt all violence passed with no apparent cease-fire Tuesday, as U.N. envoy Kofi Annan, visiting the Syrian refugee camps in Hatay, Turkey, tried to sound optimistic. But there seems little hope of a resolution to the Syrian mess anytime soon, even as talks of a cease-fire are rekindled. 

For Turkey, the events of the past year have brought serious new burdens. Nearly 25,000 Syrian refugees are living in tents in seven camps with no sense of certainty about their future. So far, the Turkish government has spent almost $85 million caring for them.

Turkey has assured Syrians from the beginning of the crisis that the border will remain open to them. Those who have fled are being given “temporary protection,” which is legally valid for at least two years.
