Israeli warplanes have reportedly fired missiles targeting Syrian military positions in Homs and the Damascus outskirts in an attack that has killed at least four civilians.
The Syrian military says Syrian air defences confronted the attack, which was launched from Lebanese airspace.
Asked about the report, an Israeli military spokeswoman declined to comment.
Syrian state-run broadcaster al-Ikhbariya said the four civilians including a baby had been killed in Sahnaya, south of Damascus, as "a result of the Zionist aggression".
A number of people were also wounded, it said, citing its correspondent.
State news agency SANA cited its correspondent as saying Syrian air defences had brought down a number of the missiles.
In recent years, Israel has carried out hundreds of strikes in Syria it says have targeted its regional arch foe, Iran, and the Lebanese Hezbollah group, which it calls the biggest threat to its borders.
Iran and Hezbollah are fighting on the side of President Bashar al-Assad in the Syrian war, and Israel says they are trying to turn Syria into a new front against Israelis.
