The Israeli military has fired a missile into Syria, the first time Israel has been drawn into the fighting in the neighbouring country.
The military said it fired the missile as a warning shot today after a stray mortar from Syria hit a military post in the Golan Heights.
Israel captured the area from Syria in the 1967 war, known as the six-day war, and subsequently annexed it.
The military says no damage or injuries were reported inside Israel.
A string of mortar shells have struck the Golan Heights during the Syrian civil war.
Israel views the fire as accidental, but nonetheless has warned that it holds Syria responsible.
