The Israeli military says it has carried out airstrikes on several military targets inside Syria in response to the fatal shooting of an Israeli teenager.
In a statement, it said nine targets – including a military headquarters – were struck from the air and land, and “direct hits were confirmed”.
Lieutenant Colonel Peter Lerner, of the Israeli military, said: “The attack was an unprovoked act of aggression against Israel, and a direct continuation to recent attacks that occurred in the area.”
There has been no immediate response from Syria.
He added that Israel “will not tolerate any attempt to breach Israel’s sovereignty and will act in order to safeguard the civilians of the state of Israel.”
On Sunday, an Israeli civilian vehicle delivering water for Israel’s Defence Ministry was struck by forces in Syria as it drove in the Israeli-controlled Golan Heights.
A teenage boy was killed and two other people were wounded in the first deadly incident along the Israeli-Syrian front since the Syria conflict erupted more than three years ago.
Israeli police named the boy as Mohammed Karaka, 14, of the Arab village of Arraba in northern Israel. Local media said he had accompanied his father, the truck driver, to work.
It is not clear whether Syrian troops or one of the many rebel groups battling the government carried out the attack which occurred in the area of Tel Hazeka, near the Quneitra crossing.
Israeli prime minister Benjamin Netanyahu accused the attackers of indiscriminate killing of Israeli citizens.
“The enemies of the state of Israel use all means, they don’t hesitate to attack civilians and kill children … they do not differentiate between Israel’s Jewish and non-Jewish citizens,” he said.
The escalation in violence adds to the tense situation in Israel, where forces have spent the past week and a half searching the West Bank for three teenagers believed to have been abducted by Hamas militants.
