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.

Israeli warplanes pounded Syrian government buildings in Damascus, escalating its campaign against Syria’s new authorities amid heavy clashes between government forces and the country’s Druze minority.

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.
