Four Israelis were treated for trauma this morning after a rocket assumed to be a Kassam was fired at the northern Gaza community of Nisanit. A house was heavily damaged in the attack. Shortly afterwards, three more shells landed in Nisanit; they led to no casualties, but caused property damage. A few minutes later, two more shells were fired at N'vei Dekalim - the largest Jewish Gaza community, located in Gush Katif, in southern Gaza. Again, no one was hurt, but a building was damaged. The barrage was accompanied by shooting attacks by Arab gunmen at several IDF outposts in the area.
