Israel vowed no let-up in its aerial bombardment of Gaza, which has claimed more than 162 Palestinian lives, as a defiant Hamas rained more rockets on the Jewish state. Both sides have dismissed calls for a truce, and Israel continued to build up troops along the Gaza border ahead of a possible ground invasion, warning Palestinians in northern Gaza to evacuate their homes. Israeli navy commandos launched a ground operation overnight in the north of the Gaza Strip, the first since the offensive against Hamas began, Israeli public radio said early Sunday.
