JERUSALEM, Oct. 19 (Xinhua) -- Israel said Thursday that its army attacked a Syrian army post, hours after a stray projectile from Syria hit the Israeli-held Golan Heights.
"The IDF (Israel Defense Forces) targeted the sources of the fire in the Syrian Golan Heights," a military spokesperson said in a statement.
The Syrian rocket prompted sirens in the Golan but caused no injuries or damage, according to the military.
The spokesperson noted that Israel holds President Bashar Assad's regime "responsible for any aggression from within its territory."
He added that the military "will not tolerate any attacks threatening the Israeli sovereignty and the safety of its civilians."
The incident came three days after Israeli aircrafts bombed an anti-aircraft battery of the Syrian army.
Israel said the airstrike was carried out in response to an earlier incident, in which an anti-aircraft missile was launched at Israeli war jets that were flying over neighboring Lebanon on a "routine reconnaissance activity," according to Israel's military.
Errant fire from the Syria's six-year-long war has occasionally been spilling over to Israel, usually causing no casualties or damage.
Israel often retaliated the mortars with airstrikes.
Israel had repeatedly declared it would not intervene in the internal fighting in Syria.
However, it is widely believed that Israel often carried out airstrikes on weapons convoys in Syria, and has been providing medical treatment to hundreds of wounded Syrians who reached the border.
