155 killed as Israel hits back at Hamas

Israeli warplanes retaliating for rocket fire from Gaza pounded dozens of security compounds across the Hamas-ruled territory in unprecedented waves of air strikes today, killing at least 155 and wounding more than 310 in the bloodiest day in Gaza in decades.

Hamas said all of its security installations were hit and in response fired several medium-range missiles at Israel, reaching deeper than in the past. One Israeli was killed and at least four were wounded.
