Israel's overnight strikes on areas in the outskirts of Damascus and the central province of Homs killed 15 people, among them three children, a monitor group says.
The Britain-based Syrian Observatory for Human Rights said six civilians were killed in the area of Sahnaya in the countryside of Damascus, but added that it was not immediately clear if they were killed in the air strikes or from huge pressure caused by the blasts in the area.
It added that nine members of militias loyal to the Syrian government were also killed as a result of the air strikes. One was a Syrian citizen and the rest were non-Syrians.
Syrian air defences on Sunday intercepted "hostile Israeli missiles" near the capital Damascus and the central province of Homs, official news agency SANA reported.
The missiles, fired by Israeli warplanes from Lebanese airspace, were targeting Syrian government military positions, SANA added.
