Israeli air strikes attacked Gaza on Sunday, killing at least a dozen people, after Prime Minister Benjamin Netanyahu warned the bloody offensive would continue as long as necessary.

Palestinian health officials say 2,115 people, most of them civilians and more than 400 of them children, have been killed in the Gaza Strip since July 8, when Israel launched an offensive with the declared aim of ending Palestinian rocket fire into its territory. Sixty-four Israeli soldiers and four civilians in Israel have been killed.
