Another suicide bomber struck in central Jerusalem Wednesday, killing one.
Officials said the bomber's explosives apparently detonated early, killing him and injuring three Israelis near the David Citadel hotel, formerly the Hilton.
The attack comes after Israeli combat helicopters fired missiles into a police building 100 feet from Palestinian Authority President Yasser Arafat's headquarters Tuesday while he was inside, amid an escalating military offensive launched across the West Bank and Gaza Strip.
Arafat was not injured in the strike in Ramallah but abruptly moved to an underground bunker.
The Israeli army said it was not trying to hit Arafat, but the strike was heavy in symbolic significance, in effect hitting the Palestinian leader where he lives.
Tuesday's strikes were wide in geographical scope, with warplanes and helicopters bombarding at least eight targets in five cities and towns.
Elsewhere, Israel expanded its newly declared \war on terror,"" launched in the wake of an especially devastating trio of Palestinian suicide bombings that killed 28 people and wounded dozens of others in 12 hours over the past weekend.
