Israeli strikes killed 42 Palestinians in the Gaza Strip on Sunday, the worst daily toll yet in almost a week of deadly clashes, as the UN Security Council met amid global alarm at the escalating conflict.
UN Secretary-General Antonio Guterres pleaded for an immediate end to the "utterly appalling" violence and warned of an "uncontainable security and humanitarian crisis".
But the council meeting, already delayed by Israel's ally the US, resulted in little action.
The heaviest exchange of fire in years, sparked by unrest in Jerusalem, has killed 197 in Gaza since Monday, along with 10 in Israel, according to authorities on either side.
Israel yesterday morning said its "continuing wave of strikes" had in the past 24 hours struck over 90 targets across the crowded coastal enclave, where an Israeli strike that destroyed a building housing journalists' offices sparked international outrage.
The death toll kept rising in Gaza yesterday as rescuers extracted bodies from vast piles of smoking rubble and the bereaved wailed in grief.
"We were sleeping and then all of a sudden there were rockets raining down on us," said Lamia al-Koulak, 43, who lost siblings and their children in dawn bombardment.
"The children were screaming. For half an hour we were bombarded without prior warning. We came out to find the building next door flattened."
But Israeli Prime Minister Netanyahu said the campaign would "take time".
Israel's army yesterday said about 3,000 rockets had been fired from the coastal strip towards Israel — the highest rate ever recorded.
Around 450 fell within the Gaza Strip, while the Iron Dome anti-missile system intercepted over 1,000, the army claimed.
Rockets have wounded over 280 people, hitting districts that had previously been well beyond the range of Hamas rockets.
At least 58 children have died in Gaza, local health authorities said, more than 1,200 people have been wounded and entire city blocks smashed to rubble.
Gaza health authorities said 40,000 people had been displaced from their homes since Monday.
Save the Children warned that life-saving services were "at breaking point" after Israeli strikes damaged power lines.
"Now basic supplies and power are running low, compounding and further fuelling this humanitarian catastrophe," said the charity's country director Jason Lee.
Palestinian Foreign Minister Riyad al-Maliki urged the UN Security Council to act, accusing Israel of "war crimes and crimes against humanity". But Israel's UN ambassador blamed Gaza fighters for the bloodshed.
The Israeli army said it had targeted the infrastructure of Hamas.
Israeli air strikes also hit the home of Yahya Sinwar, head of Hamas's political wing in Gaza, the army said, releasing footage of plumes of smoke and intense damage, but without saying if he was killed.
Balls of flame and a cloud of debris shot into the sky Saturday afternoon as Israel's air force flattened the 13-floor Gaza building housing Al Jazeera and AP news agency, after giving journalists just an hour to evacuate.
Netanyahu yesterday defended the strike.
AP called for an independent investigation.
Al Jazeera's Jerusalem bureau chief, Walid al-Omari, accused Israel of trying "to silence media that are witnessing, documenting and reporting the truth."
The conflict has sparked inter-communal violence between Jews and Arab-Israelis, and deadly clashes in the occupied West Bank, where 19 Palestinians have been killed since Monday.
A rocket yesterday damaged a synagogue in the southern Israeli city of Ashkelon.
And a car-ramming attack wounded six police officers in the flashpoint Sheikh Jarrah neighbourhood of Israeli-occupied east Jerusalem yesterday, police said, adding that the attacker was "neutralised".
Sheikh Jarrah has been at the heart of the flare-up in violence, seeing weeks of clashes between Palestinians and Israeli security forces who have cracked down hard on protests against the planned expulsion of several Palestinian families from their homes there.
Palestinians have also been outraged by police actions against worshippers protesting at the flashpoint Al-Aqsa mosque compound.
China yesterday accused the US of blocking a UN Security Council statement on the violence.
"Simply because of the obstruction of one country, the Security Council hasn't been able to speak with one voice," said Foreign Minister Wang Yi.
The US, Israel's main ally, had delayed the council session and has shown little enthusiasm for a resolution.
President Joe Biden's administration says it is working behind the scenes and that a Security Council statement could backfire.
The Biden administration has publicly backed Israel, while urging de-escalation.
