GAZA CITY, Gaza Strip (AP) -- In the three weeks of war with Israel, residents of Gaza hadn't seen the kind of bombardment that Israel unleashed today.
The heavy strikes came a day after Israel's prime minister warned of a "prolonged" campaign against Hamas.
Palestinian officials say ten members of one family were among at least 100 Palestinians killed in today's Israeli air strikes and tank shelling. Israeli warplanes carried out dozens of attacks, leveling the home of the top Hamas leader in Gaza.
Israel's escalation of its campaign in Gaza is dealing a new blow to international efforts to reach a sustainable truce.
The only power plant in the Gaza Strip has been shut down, after Palestinian officials said it was hit by Israeli tank shells. Hours after the plant was hit, a tall column of thick black smoke was still rising from a burning fuel tank.
The shutdown is expected to lead to further serious disruptions of the flow of electricity and water to the 1.7 million people packed into the narrow Palestinian territory.
