The Syrian government has not commented on the airstrikes, which the Israeli military said hit nine targets early today inside Syria.
The raids were in response to a cross-border attack the previous day that killed an Israeli civilian.
The director of the Britain-based Syrian Observatory for Human Rights, Rami Abdurrahman, said the nine Israeli strikes hit seven different Syrian military targets, destroying two tanks, two artillery batteries and the headquarters of Syria's 90th brigade.

On several occasions, artillery rounds have landed on the Israeli side of the de facto border, drawing limited Israeli reprisals.
Israel also has carried out several airstrikes in Syria over the past three years, primarily targeting suspected weapons shipments allegedly destined for Hezbollah militants in neighbouring Lebanon.
The latest air raids, however, came after an Israeli civilian vehicle was struck by fire from the Syrian side of the border as it drove in the Israeli-controlled Golan Heights.
The Israeli vehicle was delivering water as it was doing contract work for Israel's Defence Ministry when it was struck.
