Israel continues attacks across Gaza as hopes for cease-fire fade

Battles raged across Gaza on Sunday as Israel indicated it was prepared to fight for months or longer to defeat the territory's Hamas rulers, and a key mediator said willingness to discuss a cease-fire was fading.

Israel faces international outrage after its military offensive, with diplomatic support and arms from close ally the United States, has killed thousands of Palestinian civilians. About 90% of Gaza's 2.3 million people have been displaced within the besieged territory, where U.N. agencies say there is no safe place to flee.

The head of the U.N. in Gaza on Sunday described the situation as the worst he's ever seen, warning of a total humanitarian collapse inside the territory.
