A top Israeli military official says international sanctions against Iran are cutting its flow of aid and weapons to anti-Israel Hezbollah militants in Lebanon.

Even so, he says the Lebanese guerrilla group remains a potent force with an arsenal far larger and of higher quality than it possessed during a monthlong war against Israel in 2006.

Speaking Monday, the official said Hezbollah possesses tens of thousands of rockets and missiles capable of striking deep inside Israel.

Israel has expressed concerns that Syria's chemical weapons might fall into the hands of Hezbollah as the Syrian civil war deepens. The official said for now, the Syrian government appears to be maintaining control over its chemical weapons arsenals.

The official spoke on condition of anonymity under military rules.
