Israel has launched air strikes at military positions of Syrian government forces near Damascus and in the central province of Homs, Syria’s state-controlled media reports.
The report by state news agency SANA quoted unnamed Syrian military sources as saying missiles were launched from Israeli warplanes that were flying in Lebanese airspace early on July 1.
SANA said four civilians were killed and 21 injured by one of the air strikes at the town of Sahnaya to the southwest of Damascus.
The Israeli military has not commented on the claims.
The Syrian Observatory for Human Rights, a Britain-based monitor, said the air attacks hit several Iranian positions near Damascus and a research center and a military airport west of the city of Homs where the Hezbollah Shiite movement and Iranians are deployed.
Rami Abdel Rahman, the observatory chief, said the strikes injured some of these forces.
Israel has carried out hundreds of air strikes against what it describes as Iranian targets in Syria and those of allied militia, including Lebanon's Shi'ite militant group Hizballah.
The strikes have caused friction between Israel and Russia, which along with Iran has provided Syrian President Bashar al-Assad with crucial military support throughout the conflict in Syria.
The war, now in its ninth year, began with a government crackdown on protesters in March 2011. It has killed more than 370,000 people and displaced millions.
