After a mortar shell exploded on the Israeli side of the Golan Heights, the Israeli Air Force on Monday struck a Syrian military missile launcher near Quneitra.

The mortar fell in an open area and no warning sirens were activated. No casualties or damages were reported.

While the shelling was considered part of internal fighting in the Syrian region, the Israel Defense Forces (IDF) said that Syria is still responsible for errant fire occurring in its borders and any effort to threaten Israeli sovereignty or its citizens won’t be tolerated.

This is the second counter strike from Israel within two days, the first being an airstrike on Hamas targets after rocket fire hit Sderot, near Gaza on Sunday.
