Israel says it has hit dozens of targets in Syria belonging to the Syrian government and Iranian forces.
The Israeli military says the “wide-scale strikes” responded to rockets fired by an Iranian unit into Israel.
Syria says two civilians died and that Syrian air defences shot down most of the missiles over Damascus. Other reports say the death toll was higher.
Local reports said loud explosions were heard in the capital. Pictures on social media showed a number of fires.
On Tuesday morning, the Israeli military said it had intercepted four rockets fired from Syria towards northern Israel. It said the rockets did not hit the ground.
Israel is believed to have carried out hundreds of strikes in Syria since civil war broke out there in 2011, to try to prevent Iran gaining a foothold.

“During our strike of Iranian & Syrian terror targets, a Syrian air defence missile was fired despite clear warnings to refrain from such fire. As a result, a number of Syrian aerial defence batteries were destroyed,” the IDF said.
The Israeli military also said it held “the Syrian regime responsible for the actions that take place in Syrian territory and warn them against allowing further attacks against Israel”.
Iran’s Quds Force is the external operations wing of the Islamic Revolution Guard Corps (IRGC).
Both the Quds Force and its leader, Maj Gen Qasem Soleimani, answer directly to Iran’s Supreme Leader, Ayatollah Ali Khamanei, bypassing Iran’s conventional military structures to become effectively an independent entity.
What did Syria say?
Syria’s state news agency Sana said that the country’s “air defence confronted the heavy attack and intercepted the hostile missiles”.
It said that Syria destroyed “most” of the Israeli missiles.
The news agency added that the strikes on Syrian territory were carried out from “Lebanese and Palestinian territories”.
Israel has a number of times hit targets inside Syria from war planes in Lebanese airspace.
Syria said two civilians were killed in the Israeli strikes.
Meanwhile, a UK-based monitoring group, the Syrian Observatory for Human Rights, said that 11 fighters, including seven foreigners, died.
And what about Iran?
The Iranian authorities have so far made no public comment.
