The Israeli Air Force attacked military targets on the Syrian side of Golan Heights overnight into Thursday in response to a projectile from Syria the day before, according to the Israeli army.
An Israeli plane fired at least three missiles into the northern Queintra countryside, according to the Britain-based Syrian Observatory for Human Rights, adding no casualties were reported.
According to Syrian military sources, four soldiers were injured in the attack and a mortar launcher was destroyed.
The attack was in response to a projectile that hit an undeveloped area in the Israeli-controlled part of the Golan Heights on Wednesday afternoon, the Israeli army said. Israel reported no injuries.
The Israeli military in the past has launched shells and airstrikes in response to bombs that landed in Golan Heights during battles in the Syrian conflict.
Israel captured the strategic plateau, overlooking the Sea of Galilee, from Syria in the 1967 Six-Day War
