IDF infantry troops and some 40 tanks raided a Hamas stronghold in the Sajaiye neighborhood in Gaza last night. The forces destroyed four explosives labs and 32 weapons-making lathes used for making mortar shells and Kassam rockets. Calls were sounded over mosque loudspeakers last night for the Arab residents to take up arms and fight the Israelis; 11 Arabs were killed and over 20 wounded, while our side suffered no casualties. The battle commander said that his forces were met with fierce Arab resistance, including eight anti-tank bombs as the forces were entering the town. The bombs damaged some vehicles.
