GAZA CITY, Gaza Strip —
Missiles also knocked out five electricity transformers, plunging more than 400,000 people into darkness, according to the Gaza electricity distribution company.
A separate airstrike leveled a mosque in central Gaza, damaging nearby houses, Gaza security officials and residents said. The military had no comment on that attack and it wasn't clear whether weapons or fighters were being harbored in the area.
One person was killed and three dozen people were wounded in the various attacks, Gaza health official Ashraf al-Kidra said. In all, 30 Palestinians and three Israelis have been killed since the Israeli operation began.
The Israeli military said it did not immediately have an accounting of its various overnight targets.
"The Palestinian government emphasizes its steadfastness and support for the Palestinian resistance," government spokesman Ihab Hussein said in a text message to reporters after the wave of Israeli attacks. "It stands alongside its people, who are subject to this aggression."
The widened scope of targets brings the two sides closer to the kind of all-out war they waged four years ago. Hamas, a group committed to Israel's destruction, was badly bruised during that confrontation, but has since restocked its arsenal with more and better weapons, and has been under pressure from smaller, more militant groups to prove its commitment to armed struggle against Israel.
The attack aimed at Jerusalem on Friday and strikes on the Tel Aviv area twice this week dramatically showcased the militants' new capabilities, including a locally made rocket that appears to have taken Israeli defense officials by surprise. Both areas had remained outside the gunmen's reach in past rounds of fighting, and their use dramatically escalated the hostilities.
Just a few years ago, Palestinian rockets were limited to crude devices manufactured in Gaza. But in recent years, Israeli officials say, Hamas and other armed groups have smuggled in sophisticated, longer-range rockets from Iran and Libya, which has been flush with weapons since Moammar Gadhafi was ousted last year.
