The Syrian Observatory for Human Rights, a British-based war monitor, said the attacks were aimed at pro-Iranian groups in the provinces of Homs and Hama, hitting weapons and ammunition sites.
The Syrian Observatory also said that Israeli forces targeted a Syrian air defence battery in Latakia province.
Syria’s air defences counter-attacked, causing material damage, SANA reported.
There has been no comment from the Israeli military.
Israel has carried out hundreds of strikes on targets inside government-controlled parts of Syria in recent years, but rarely acknowledges or discusses the operations.
However, Israel has acknowledged that it targets the bases of Iran-allied fighters, such as Lebanon’s Hezbollah, which has backed Syrian President Bashar al-Assad’s forces by sending in thousands of fighters.
On November 13, Israeli air attacks killed two Syrian soldiers and wounded three in the central province of Homs, Syrian state media reported.
The war in Syria started in 2011 after the government responded violently to the country’s protest movement. Hundreds of thousands of people have been killed and half the country’s pre-war population of 23 million has been displaced.
