THE HAGUE (Reuters) -Israeli airstrikes on Damascus are hampering Syria's efforts to find and destroy chemical weapons stockpiled during the rule of toppled ruler Bashar al-Assad, a government adviser said on Thursday.

Clashes raged in the southern Syrian city of Sweida on Wednesday after a ceasefire between government forces and Druze armed groups collapsed and as Israel threatened to escalate its involvement, saying it's in support of the Druze religious minority.
