Israel says it has no proof chemical weapons used in Syria

Israel voiced doubt on Tuesday about the accuracy of Syrian activists' reports that chemical weapons had been used against rebels fighting to topple President Bashar al-Assad, Reuters reports.

"We have seen reports from the opposition. It is not the first time. The opposition has an interest in drawing in international military intervention," Vice Prime Minister Moshe Yaalon said on Army Radio.

"As things stand now, we do not have any confirmation or proof that (chemical weapons) have already been used, but we are definitely following events with concern," he said.
