A Grad missile fired by Palestinian terrorists in Gaza landed in a residential neighborhood in Beersheba Wednesday night, causing severe damage but no injuries. Four people were treated for shock, paramedics said. It was the first rocket to land in the city since the army concluded Operation Cast Lead, a three week offensive in Gaza to rout out terror groups that began in December 2008 and ended in January 2009. A total of five mortar shells were fired at the western Negev in southern Israel on Wednesday the army said. No one was injured in any of the incidents, the shells reportedly fell inside one of the kibbutzim near the Gaza Strip and open areas in the region. During the day Palestinian terrorists detonated an explosive device and fired a mortar shell at troops patrolling the Gaza border fence. No one was injured in the attacks. In response, the army fired tank shells towards the perpetrators. Palestinian media in Gaza reported eleven Palestinians were injured, two seriously.
