Israeli warplanes flying over Lebanon fired missiles towards areas near the Syrian capital of Damascus, hitting an arms depot and wounding three soldiers, Syrian state media reported.
State TV said that most of the missiles were shot down by air defence units.
The TV, quoting an unnamed military official, identified the warplanes as Israeli.
Lebanon's state-run National News Agency earlier reported that Israeli warplanes were flying at low altitude over parts of southern Lebanon.
The Britain-based Syrian Observatory for Human Rights, a war monitor, said Israeli airstrikes targeted three positions south of Damascus that are arms depots for Lebanon's militant Hizbollah group and Iranian forces.
