JERUSALEM (CBS News) -- The Israeli military says it has fired into Syria for a second straight day in response to errant mortar fire that landed in the Israeli-controlled Golan Heights.
There were no reports of injuries on either side of the frontier Monday.
But a series of similar incidents in recent days has raised fears that Israel could be dragged into the fighting in its northern neighbor.
Israel does not believe the mortar fire has intentionally targeted Israeli targets.
Still, Israeli officials have warned that they will respond harshly if the attacks persist.
Israel responded for the first time on Sunday, firing an anti-tank missile as a "warning shot."
