The IDF fired a warning shot at the Syrian military on Sunday, after a Syrian shell landed in the Golan Heights for the second time in recent days .
Israel has not fired at Syria since the 1973 Yom Kippur War.
“In the midst of Syrian infighting, a mortar shell fired by the Syrian army struck near an outpost at Tel Hazeka,” IDF spokesman Brig.-Gen. Yoav Mordechai said. The shell failed to cause injuries or damages.
“In light of the policy instituted by IDF Chief of Staff, Lt.-Gen. Benny Gantz, a warning round was fired back into Syria. We don’t believe it caused injuries or damages,” Mordechai added.
At the same time, Israel sent a warning message to the UN, saying that any further firing into Israel will result “in a real response,” sources added.
