Palestinian terrorists barraged Israel with more than 200 rockets on Thursday, killing three people as Israel pressed a punishing campaign of airstrikes on militant targets across the Gaza Strip.
Three rockets targeted the densely populated Tel Aviv area, setting off air-raid sirens in brazen attacks that threatened to trigger an Israeli ground invasion of Gaza.
Late in the day, Israel signaled a ground operation may be imminent as forces moved toward the border area with Gaza. At least 12 trucks were seen transporting tanks and armoured personnel carriers, and a number of buses carrying soldiers arrived.
Israeli Defence Minister Ehud Barak said he had authorized the army to call-up additional reservists for possible action. The army said it was prepared to draft up to 30,000 additional troops.
