Israeli troops fired warning shots into Syria on Sunday, the Israeli military said in a statement, in what public radio said was the first Israeli fire directed at the Syrian military since the 1973 war.

"A short while ago, a mortar shell hit an IDF post in the Golan Heights adjacent to the Israel-Syria border, as part of the internal conflict inside Syria. In response, IDF soldiers fired warning shots towards Syrian areas," the army said in a statement.
