The army said Israeli jets hit an army outpost in Salamiya and another in Sabura towns in Hama province only hours after missiles struck other military installations in Deir al Zor province along the border with Iraq and in southern Syria near the border with Jordan.
Earlier an army statement said several attacks occurred simultaneously, one at a military outpost in Kabajib, east of Deir Zor province and in the vicinity of the town of Sukhna in the nearby eastern desert. A third strike hit a military installation farther south in the town of Salkhad, near the southern city of Sweida. Two soldiers died and four were wounded.
The bases are in zones in eastern and southern Syria which Israel had hit in recent months and which are believed to have a strong presence of Iranian-backed militias.
A senior Syrian military defector and a regional intelligence source said an Iranian arms depot near the city of Salamiya was set on fire after it was repeatedly bombed while a command centre in the town of Sabura run by Iranian militias was also severely damaged.
