Israel bombs Gaza government buildings Israel bombed the offices of the Hamas prime minister in Gaza and several other government buildings overnight, amid reports that the government had authorised the call-up of up to 75,000 more reserve soldiers in preparation for a ground war. The latest developments pointed towards further escalation, and came after Hamas on Friday fired the first-ever rocket from Gaza at Jerusalem, and targeted the coastal city of Tel Aviv for the second day in a row. The overnight Israeli air strikes took the overall Palestinian death-toll to at least 39 in four days of fighting. In addition, at least 350 Gazans have been wounded by Israeli fire. Three Israelis were killed by rocket fire from Gaza on Thursday. Hamas and other Gaza-based militant groups resumed their rocket fire on Israeli towns and villages on Saturday morning, though the intensity of the bombardment appeared to be on the wane. The Israeli military said its overnight strikes were aimed at government buildings as well as "several rocket launching squads that were involved in firing rockets at Israel." It also claimed to have hit a Hamas training facility in the northern Gaza Strip. Friday's rocket attack was the first time that rocket fire from Gaza has reached the vicinity of Jerusalem, Israel's largest city and government seat. The attack caused no injuries and no damage, but was a warning that Hamas and other groups still have the ability to strike deep inside Israel despite three days of heavy bombardment. The Hamas military wing claimed responsibility for the rocket. Israeli leaders have said their bombardment of Gaza this week is designed to deter Hamas. The Israeli military said on Friday it had bombed at least 600 sites inside the strip since the first strike on Wednesday, which killed the leader of the Hamas military wing. Suggesting it was preparing for a protracted conflict, the Israeli army also announced that it was calling up 16,000 reserve soldiers to bolsters its ranks. Israeli TV reported the government was considering increasing the number of reservists to 75,000..
