Israel raids on Syria, Hezbollah targets since 2013

Israel, which launched deadly air strikes Thursday and Friday on the Syrian side of the Golan Heights, has carried out several attacks on Syrian military positions since January 2013.

It has also targeted the powerful Lebanese Shiite movement Hezbollah, a key ally of Syrian President Bashar al-Assad.
