Israeli airstrikes and tanks shells continued on Gaza on Friday night, killing forty more people, which rose the death toll to 801 since the beginning of the Israeli military offensive on Dec. 27, a senior Gaza official said. Gaza emergency chief Mo'aweya Hassanein released the figures to reporters, saying that now 801 Palestinians were killed and 3300 were injured. The dead included 230 children and 92 women, he added. Earlier on Friday, Israeli army warplanes and tanks launched a series of air and ground strikes on houses in central and northern Gaza Strip, killing at least 21 people and wounded 60 others, according to Hassanein. The Israeli army has been carrying out continuous military air and ground operations for 14 days, during which hundreds of buildings, including homes, mosques and security installations were destroyed by missiles and bombs.
