Israel strikes media buildings in Gaza,

The Israeli military struck two buildings used by journalists in Gaza early Sunday during the fifth day of a campaign against militants in the Palestinian enclave. Hours later, artillery rounds landed in southern Israeli cities and the country’s missile defense system intercepted a powerful long-range rocket over Tel Aviv, the second such incident in as many days.

Sunday’s strikes in Gaza suggested Israel is continuing to expand its range of targets after hitting almost exclusively military sites during the first few days of the operation, dubbed Pillar of Defense. On Saturday, an Israeli bomb demolished the office of Hamas Prime Minister Ismail Haniyeh. The crossfire dimmed hopes for a ceasefire as Arab leaders led by Egyptian President Mohamed Morsi were set to convene in Cairo on Sunday to discuss a negotiated end to the conflict.

“We are extracting a heavy price from Hamas and the terror organizations,” Israeli Prime Minister Benjamin Netanyahu said Sunday during the opening session of the weekly cabinet meeting. “The army is prepared to significantly expand the operation.”

The sites hit in Gaza early Sunday included buildings used by Britain’s Sky News channel and the Dubai-based pan-Arab broadcaster al-Arabiya, the news organizations reported. At least six journalists were wounded, according to a health ministry spokesman in Gaza quoted by wire services.

One of the buildings was used by al-Quds channel, which serves as a mouthpiece for Hamas, the militant group that rules Gaza. The Foreign Press Association in Israel issued a letter expressing concern and noting that a United Nations Security Council resolution says that journalists covering conflict civilians that must be protected.

The Israeli military said the sites struck overnight included a “communications antenna used by Hamas to carry out terrorist activity.” In a statement, it said it also hit dozens of underground rocket launchers and a Hamas training base.

Avital Leibovich, an Israeli military spokeswoman said Sunday that the media buildings struck included key Hamas communication infrastructure.

“The target was not journalists,” she told reporters in Jerusalem. “The journalists in these buildings were serving as human shields for Hamas.”

Leibovich said the prospect of a ground operation remains “on the table,” but that the country’s leaders have not yet decided whether to deploy troops into Gaza.

A nighttime lull in rocket fire from Gaza ended shortly after 8 a.m. as rockets landed in Ashkelon and Eshkol, southern Israeli cities. Around 10:30 a.m., the artillery warning siren in Tel Aviv rang out seconds before a long-range rocket was blasted overhead by the country’s anti-missile system, known as Iron Dome. Local media reported that a vehicle struck by debris caught on fire.

Israel’s offensive in the Gaza Strip expanded to target Hamas government buildings on Saturday. Palestinian militants continued firing a torrent of rockets at civilian areas in southern Israel as both sides stepped up diplomatic efforts to win support.

Israeli airstrikes over Gaza accelerated to nearly 200 early in the day, including one hit that reduced the offices of Hamas Prime Minister Ismail Haniyeh to a smoldering concrete heap. That strike, along with others on a police headquarters and smuggling tunnels along the strip’s southern border with Egypt, raised questions about whether Israel had broadened its mission to including toppling the Hamas government that rules the coastal strip.

Just before sundown on Saturday, Hamas said it had fired an Iranian-made Fajr-5 rocket at Tel Aviv, and air raid sirens sounded in that city for the third day in a row. The Israeli military said its newly deployed missile defense battery intercepted the rocket before it landed in the populous coastal city.

Even as airstrikes pounded the area Saturday morning, the foreign minister of Tunisia’s Islamist-led government, Rafik Abdessalem, arrived in Gaza with a delegation, underscoring Hamas’s newfound credibility in a region dramatically altered by the Arab Spring. Abdessalem expressed outrage at what he called Israeli “aggression” and pledged to unite with other Arab countries to end the conflict.

In Cairo, Egyptian President Mohamed Morsi, whose prime minister visited Gaza on Friday, held meetings with Turkey’s prime minister, Recep Tayyip Erdogan, and the emir of Qatar, Sheik Hamad Bin Khalifa al-Thani — both Hamas supporters — to discuss what Morsi and other regional leaders have promised will be a more robust response to Israel’s actions than during past conflicts. By Saturday night, rumors of Morsi, Erdogan and Hamas chairman Khaled Meshal hashing out a cease-fire plan were swirling but unconfirmed.

Also in Cairo, the Arab League held an emergency meeting of foreign ministers to discuss a response to the conflict. Many participants called for Arab assistance to the Palestinians and a “reconsideration” of Egypt’s peace treaty with Israel. But it was unclear if the usually ineffectual league would deliver decisive action by the end of its summit.

Israeli Prime Minister Benjamin Netanyahu, meanwhile, took his country’s case to European leaders. In conversations with German Chancellor Angela Merkel and the prime ministers of Italy, Greece and the Czech Republic, Netanyahu argued that “no country in the world would agree to a situation in which its population lives under a constant missile threat,” according to an Israeli government statement. The government announced that it was launching a special operations center for public diplomacy, centered on “the unified message that Israel is under fire.”

The White House reiterated its support for the Israeli operation, which the military says is intended to stop rocket fire that has escalated in the four years since Israel last invaded Gaza to stunt attacks by Hamas, an Islamist movement that Israel and the United States consider a terrorist group.

“Israelis have endured far too much of a threat from these rockets for far too long,” Ben Rhodes, a deputy U.S. national security adviser, told reporters traveling with President Obama to Asia. Rhodes declined to comment on the Israelis’ choice of targets, but he said White House officials “always underscore the importance of avoiding civilian casualties.”

The death toll in Gaza rose to 45 by Saturday evening, Health Ministry officials said. Three Israelis have been killed by rocket fire from Gaza since the operation began. An Israeli military spokesman said about 130 rockets were fired from Gaza at Israel on Saturday, 30 of which were intercepted by a missile defense system known as Iron Dome.

Israel made preparations this week for a possible ground invasion, but there were no further signs of one coming on Saturday.

Israel: No shift in mission

The Israeli airstrikes, which continued to target rocket-launching sites and weapons depots, slowed throughout the day, even as Israel appeared to be channeling new efforts toward Hamas civilian institutions. Capt. Eytan Buchman, an Israeli military spokesman, said the strikes were “part of our overarching goal of toppling Hamas’s command and control capabilities” and did not mark a shift in mission.

Haniyeh, the Hamas prime minister, was apparently not at his office when it was hit.

According to the newspaper Haaretz, Israeli Interior Minister Eli Yishai said the “goal of the operation is to send Gaza back to the Middle Ages.”

That is how it felt to Hossam and Sanaa al-Dadah, two teachers who had the misfortune of living next door to a house the Israeli military said belonged to a Hamas commander.

At 6 a.m., the family’s windows shattered and their walls burst open. The adjacent house, in the Jabaliya refugee camp, had been demolished in an airstrike, and suddenly theirs was ruined, too.

In the terrifying moments that followed, Hossam al-Dadah, 50, frantically dug his five children out of the rubble, and a few hours later, they had been taken away to their grandparents’ home. But a dust-caked Sanaa, 40, rushed from room to room, crying and gathering her children’s clothing, school bags and dolls and placing them on a sheet.

Israel says Hamas operates in populated areas to use civilians as human shields, and it has dropped thousands of leaflets over Gaza warning civilians to stay away from Hamas operatives. Sanaa said she never got the message.

“Where are we going to go?” she said again and again. “The Israelis are responsible. They are the enemy of God. What did we do? Did we carry any missiles? Did we launch any rockets?”

Outside the house, children played insouciantly in rubble and scorched cars. Rami Mukayed, a 12-year-old in gray trousers, said he reserved his fear for darkness.

“At night, come see me, I’m panicked,” he said. “I play in the morning. I hide in the evening.”

Effect on peace process

In a speech in Cairo, Erdogan said the Gaza conflict called for a new era of Egyptian-Turkish cooperation.

“If Turkey and Egypt unite, everybody will be singing of peace in the region,” he said. “And if we stick together, the region will no longer be dominated by crying and weeping.”

Speakers at the Arab League meeting made the same argument.

“We can no longer accept empty meetings and meaningless resolutions,” said Arab League chief Nabil Elaraby, addressing the assembly at the start of the meeting. He urged Arab states to adopt a “strict stance” on the conflict.

Issandr El Amrani, a visiting fellow at the European Council on Foreign Relations who heads a blog called the Arabist, said the Gaza standoff has presented the new Arab Spring governments and other regional heavyweights an opportunity to reconsider their position on Israel and the peace process in a series of talks that could have long-term regional implications.

For years, the Arab League has floated a proposal for an Israeli-Palestinian peace deal that Israel never took seriously, Amrani said. Arab states might now choose to drop that proposal and adopt more aggressive approaches — Egypt could revise the terms of its peace treaty with Israel; Arab states might consider providing covert aid to Hamas; and others will amplify the pressure on Israel through diplomatic corridors, he said.

By Saturday night, despite mounting rhetorical and symbolic support to Gaza’s Hamas leadership, the Arab ministers’ meeting had announced plans to send a delegation to Gaza but had stopped short of pledging immediate material support to Hamas.

“I’ve seen a lot of talk about doing something and how there’s a collective Arab responsibility to act,” Amrani said, “but no one has suggested anything concrete.”
