Mortar fire from inside war-torn Syria hit the Israeli part of the Golan Heights on Tuesday, an IDF spokeswoman said.

"Several mortar rounds fired from Syria exploded in northern Golan without causing any damage or casualties," the spokeswoman told AFP.

It was apparently stray fire from fighting between Syrian government forces and rebels and was not deliberately fired towards Israeli territory, she added.

The Golan has been tense since the beginning of the conflict in Syria more than two years ago, but so far there have been only minor flare-ups as Syrian small arms fire or mortar rounds hit the Israeli side, prompting an occasional Israeli response.
