Israel says it has carried out air strikes on military targets in Syria.
The military said it had attacked nine targets in response to the killing of a 15-year-old boy in a strike in the occupied Golan Heights on the border between the two countries on Sunday.
Two others, including the boy’s father, an Israeli defence contractor, were injured when a blast hit their vehicle.
Israel called the boy’s death the most substantial incident in the Golan since start of the Syrian conflict in 2011.
Israeli military spokesman, Lt Col Peter Lerner, told the Associated Press news agency the attack from Syria was “clearly intentional” but it was unclear whether the blast in the area of Tel Hazeka near the Quneitra crossing was the result of mortar fire, a roadside bomb or shelling.
He described it as “an unprovoked act of aggression against Israel and a direct continuation to recent attacks that occurred in the area”.

The Israeli military said its air strikes targeted Syrian army positions, including a military headquarters, in response and that “direct hits were confirmed”.
The teenager, an Arab Israeli, has been named as Mohammed Qaraqara.
“He was an excellent student, everyone loved him,” his cousin Salah Qaraqara told Reuters.
Israeli Prime Minister Benjamin Netanyahu said: “Our enemies don’t differentiate between Jews and non-Jews, adults and children.”
The Golan Heights, a rocky plateau in south-western Syria, was seized by Israel from Syria in the closing stages of the 1967 Middle East War.
The two countries remain technically in a state of war, and UN observers are deployed to monitor a 70km-long (45-mile) demilitarised zone.
Firing linked to the Syrian conflict occasionally reaches the Israeli side of the border fence – some unintentional, some said to be deliberate.
In March, Israel conducted air strikes against several Syrian military targets after a bombing that injured four of its soldiers in the Golan Heights.
