Israeli air attacks reportedly targeted Iranian Revolutionary Guard bases and weapons plant in al-Safira area of Aleppo.
Syria’s air defences have intercepted an Israeli attack on the al-Qusayr area in Homs, Syrian state media reported.
A Syrian military source said in a statement on Thursday there was some material damage from the raid but no casualties.
The Israeli military said it had no comment.
Homs province adjoins Lebanon, where the Iranian-backed Lebanese Shia Hezbollah group holds sway along the rugged border area.
Western intelligence sources have said Israel’s stepped-up raids on Syria since last year are part of a shadow war approved by the United States.
The attacks are also part of an anti-Iran policy that over the past two years has sought to undermine Iran’s extensive military power without starting a significant increase in hostilities.
