The Israeli military has fired a missile into Syria, the first time Israel has been drawn into the fighting in the neighboring 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. The military says no damage or injuries were reported inside Israel. A string of mortar shells have struck the Golan during the Syrian civil war. Israel views the fire as accidental, but nonetheless has warned that it holds Syria responsible.
