Israel pounded Gaza on Saturday, destroying a tower block that housed news media organisations, while Palestinian rocket salvoes hit Tel Aviv.
It came on a sixth day of hostilities in which Palestinians say at least 145 people, including 41 children, have been killed in Gaza since the conflict began. Israel has reported 10 dead, including two children.
The 12-storey block in Gaza City brought down by Israeli air strikes housed the U.S. Associated Press and Qatar-based Al Jazeera media operations.
However, the Israel military said it was a legitimate military target, containing Hamas military offices, and that it had given warnings to civilians to get out of the building before the attack.
The strike was condemned by the AP and Al Jazeera, and the United States told Israel “that ensuring the safety and security of journalists and independent media is a paramount responsibility,” White House Press Secretary Jen Psaki said.
U.S. President Joe Biden later spoke to both Israeli Prime Minister Benjamin Netanyahu and Palestinian President Mahmoud Abbas in an effort to restore calm.
But both Israel and Hamas insisted they would pursue their campaigns, leaving no end to the hostilities in sight despite a U.N. Security Council meeting scheduled for Sunday to discuss the worse outbreak of Israel-Palestinian violence in years.
“The party that bears the guilt for this confrontation is not us, it’s those attacking us,” Netanyahu said in a televised speech.
“We are still in the midst of this operation, it is still not over and this operation will continue as long as necessary.”
Netanyahu said Israel’s air and artillery barrage had eliminated dozens of Hamas militants and taken out “hundreds” of the Islamist militant group’s sites including missile launchers and a vast tunnel network.
Hamas began its rocket assault on Monday after weeks of tensions over a court case to evict several Palestinian families in East Jerusalem, and in retaliation for Israeli police clashes with Palestinians near the city’s Al-Aqsa Mosque, Islam’s third holiest site, during the Muslim holy month of Ramadan.
Speaking to crowds of protesters in the Qatari capital of Doha, Hamas chief Ismail Haniyeh said on Saturday the fighting was primarily about Jerusalem.
“The Zionists thought … they could demolish Al-Aqsa mosque. They thought they could displace our people in Sheikh Jarrah,” said Haniyeh.
“I say to Netanyahu: do not play with fire,” he continued, amid cheers from the crowd. “The title of this battle today, the title of the war, and the title of the intifada, is Jerusalem, Jerusalem, Jerusalem,” using the Arabic word for ‘uprising’.
On Saturday, the Israeli military said around 2,300 rockets had been fired from Gaza since Monday, with about 1,000 intercepted by missile defences and 380 falling into the Gaza Strip.
Israel has launched more than 1,000 air and artillery strikes into the densely populated coastal strip, saying they were aimed at Hamas and other militant targets.
The bombardments have sent columns of smoke above Gaza City and lit up the enclave’s night sky.
Earlier this week the International Criminal Court’s chief prosecutor, Fatou Bensouda, told Reuters the court was “monitoring very closely” the latest escalation of hostilities, amid an investigation now under way into alleged war crimes in earlier bouts of the conflict.
Netanyahu accused Hamas of “committing a double war crime” by targeting civilians, and using Palestinian civilians as “human shields.”
The New York-based rights group Human Rights Watch said on Saturday it had “serious concerns that the attacks caused disproportionate destruction of civilian property” in Gaza.
Biden’s envoy, Hady Amr, arrived in Israel on Friday, before a meeting on Sunday of the U.N. Security Council.
But diplomacy has so far failed to quell the worst escalation in fighting between Israel and Palestinians since 2014.
The White House said Biden updated Netanyahu on “high-level” contacts with regional partners to restore calm, and raised concerns about the safety of journalists.
Biden also spoke with Abbas, for the first time since the U.S. leader took office in January.
Both sides said Biden reaffirmed his support for a two-state solution to the conflict, and the White House said Biden was committed to “strengthening the U.S.-Palestinian partnership”, which reached a nadir under the Trump administration.
But diplomatic efforts are complicated by the fact the United States and most western powers do not talk to Hamas, which they regard as a terrorist organisation. And Abbas, whose power base is in the occupied West Bank, exerts little influence over Hamas in Gaza.
In Israel, the conflict has been accompanied by violence among the country’s mixed communities of Jews and Arabs. Synagogues have been attacked, Arab-owned shops vandalised and street fights have broken out. Israel’s president has warned of civil war.
Hamas said the latest strikes on Tel Aviv were in response to Israel’s overnight strikes on Gaza’s Beach refugee camp, where a woman and four of her children were killed in their house.
Five others died, medics said. Israel said it targeted an apartment used by Hamas.
