JERUSALEM — A veteran Israeli lawmaker and former defense minister says Syria's chemical weapons are "trickling" to Lebanon's militant Hezbollah group.

Binyamin Ben-Eliezer told Israel Radio on Monday that he is shocked by the "world's silence" and that the West must intervene to stop the high civilian death toll in Syria.

He says he "has no doubt" Syrian President Bashar al-Assad used chemical weapons and that some of the weapons are "definitely reaching" Israel's enemy Hezbollah.

The Israeli government convened its security Cabinet to discuss Syria late on Sunday but no details were released.

Both sides in Syria's civil war accuse each other of using chemical weapons.

The United States has warned such weapons cross a red line and last week said the weapons were probably used, though it still seeks definitive proof.
