Ten people were killed when the Israel Air Force struck several military targets in neighboring Syria early on Monday, the head of the Syrian Observatory for Human Rights.
The Israeli strikes were made in response to Sunday's cross-border missile shooting, which killed an Israeli teenager and wounded his father and two other civilians.
The strikes were carried out shortly after midnight. Nine targets belonging to the Syrian military were hit, among them command centers, according to a statement released by the Israel Defense Forces Spokesman.
Rami Abdel Rahman, head of the British-based organization, told DPA that the strikes destroyed two tanks and seven army posts. Earlier Monday, a Syrian opposition operative said that the Israeli strikes caused severe damage to Syrian army tanks, armored personnel carriers and a command center.
The Syrian government did not immediately issue a response to the attack.
An IDF officer told Haaretz the strikes were carried out using both Tamuz guided missiles and IAF jets.
The IDF Spokesman called the strikes a direct response to ongoing cross-border aggression which culminated in Sunday's deadly missile attack.
"The shooting [on Sunday] was a very serious act of provocation, and a continuation of a series of attacks carried out over the past several months against IDF forces throughout the border region, and in this area specifically," a statement read.
Defense Minister Moshe Ya'alon's office addressed the IAF strike in a statement, vowing to continue retaliating "resolutely and harshly to any provocation" or attempt to undermine Israel's sovereignty.
"We have seen repeated attempts to act against Israel from areas that are under the control of the Assad regime," the statement read. "We will not tolerate attacks on Israeli citizens or on IDF troops. Anyone who tries to disrupt our lives will pay a heavy price, whether it is the Syrian army or terrorist groups operating on Syrian territory."
Tanks respond to missile attack
On Sunday, Israeli tanks fired at positions held by Syrian government forces, after a 14-year-old Israeli boy was killed and three others were wounded when an anti-tank projectile fired from within Syria struck near the border fence on the Golan Heights.
Muhammad Fahmi Krakara was sitting in a truck with his father, who was doing maintenance work on the fence for the Defense Ministry along with two other contract workers. One employee suffered serious injuries, the father was moderately wounded and the third employee was lightly injured.
On Sunday, an Israel Defense Forces officer said it was not known whether Syrian government forces or rebels fired the anti-tank missile, though the segment of the border fence where it landed is under rebel control.
The slain boy's father and the seriously injured employee were evacuated to Rebecca Sieff Hospital in Safed, and the worker with light wounds was taken to Rambam Medical Center in Haifa.
