GAZA CITY — The top leader of Hamas dared Israel on Monday to launch a ground invasion of Gaza and dismissed diplomatic efforts to broker a cease-fire in the six-day-old conflict, as the Israeli military conducted a new wave of deadly airstrikes on the besieged Palestinian enclave, including a second hit on a 15-story building that houses media outlets. A volley of rockets fired from Gaza into southern Israel included one that hit a vacant school.
Speaking at a news conference in Cairo, where the diplomatic efforts were under way, the Hamas leader, Khaled Meshal, suggested that the Israeli infantry mobilization on the border with Gaza was a bluff on the part of Prime Minister Benjamin Netanyahu of Israel.
“If you wanted to launch it, you would have done it,” Mr. Meshal told reporters. He accused Israel of using the invasion threat as an attempt to “dictate its own terms and force us into silence.”
Rejecting Israel’s contention that Hamas had precipitated the conflict, Mr. Meshal said the burden was on the Israelis. “The demand of the people of Gaza is meeting their legimitate demands — for Israel to be restrained from its aggression, assassinations and invasions, and for the siege over Gaza to be ended,” he said.
The Hamas Health Ministry said Monday evening that a total of 102 people had been killed since Wednesday morning, when Israeli airstrikes began, following months of Palestinian rocket fire into Israel. A spokeswoman for the Israeli military said she believed that a majority of these were militants, though it is difficult to know because Hamas’s own fighting brigade and the other factional groups are secretive.
The Hamas ministry said that the dead included 24 children, 10 women and 12 men over 50, who were presumably not involved in combat. Of the remaining 56, at least 36 are known militants. Hamas officials said 850 have been wounded, 260 of them children, 140 of them women and 55 men over 50.
Three people have been killed so far in Israel, all civilians, in a rocket strike that hit an apartment house in the southern Israeli town of Kiryat Malachi on Thursday morning. The Israelis have said that at least 79 Israelis have been wounded and that Gaza rockets have reached as far north as Tel Aviv.
The latest Gaza casualties — 19 people reported killed since midnight local time — included Palestinians killed in strikes by warplanes and a drone attack on two men on a motorcycle, the Health Ministry said. Another Israeli drone attack killed the driver of a taxi hired by journalists and displaying “Press” signs, although it was not clear which journalists hired it, Palestinian officials said.
On Sunday, Israeli forces attacked two buildings housing local broadcasters and production companies used by foreign outlets. Israeli officials denied targeting journalists, but on Monday Israeli forces again blasted the Al Sharouk block, a multiuse building where many local broadcasters, as well as Sky News of Britain and the channel Al Arabiya, had offices.
That attack, which struck a computer shop on the third floor, sparked a blaze that sent plumes of dark smoke creeping up the sides of the building. Video footage showed clouds of smoke billowing.
An Israeli bomb pummeled a home deep into the ground here on Sunday, killing 11 people, including nine in three generations of a single family, in the deadliest single strike since the latest conflict began. Members of the family were buried Monday in a rite that turned into a gesture of defiance and became a rally supporting Gaza’s militant Hamas rulers.
A militant leader said Tel Aviv, in the Israeli heartland, would be hit “over and over” and warned Israelis that their leaders were misleading them and would “take them to hell.”
Israel says its onslaught is designed to stop Hamas from launching the rockets, but, after an apparent lull overnight, more missiles hurtled toward targets in Israel, some of them intercepted by Israel’s Iron Dome defense system. Of five rockets fired on Monday at the southern Israeli city of Ashkelon, four were intercepted but one smashed through the concrete roof at the entrance to an empty school. There were no reports of casualties. Other rockets rained on areas along the border with Gaza.
Later a second salvo struck Ashkelon. Several rockets were intercepted, but one crashed down onto a house, causing damage but no casualties. News reports said 75 rockets had been fired by midafternoon.
On Sunday, a new volley of Palestinian rockets totaled nearly 100 by nightfall, including two that soared toward Tel Aviv but were knocked out of the sky by Israeli defenses.
