Israeli warplanes struck two refugee camps in the Gaza Strip early Sunday, killing at least 53 people and wounding dozens, health officials said. The strikes came as Israel said it would press on with its offensive to crush the territory鈥檚 Hamas rulers, despite U.S. appeals for a pause to get aid to desperate civilians.

Israel has rejected the idea of halting its offensive, even for brief humanitarian pauses proposed by U.S. Secretary of State Antony Blinken during his current . Gaza鈥檚 Health Ministry said more than 9,700 Palestinians have been killed in the territory in nearly a , a number that is likely to rise as Israeli troops advance into dense, urban neighborhoods.

Airstrikes hit the Maghazi refugee camp in central Gaza overnight, killing at least 40 people and wounding 34 others, the Health Ministry said.

An Associated Press reporter at a nearby hospital saw eight dead children, including a baby, who were brought in after the strike. A surviving child was led down the corridor, her clothes caked in dust, an expression of shock on her face.

Arafat Abu Mashaia, who lives in the camp, said the Israeli airstrike flattened several multi-story homes where people forced out of other parts of Gaza were sheltering.

鈥淚t was a true massacre,鈥� he said while standing on the wreckage. 鈥淎ll here are peaceful people. I challenge anyone who says there were resistance (fighters) here.鈥�

There was no immediate comment from the Israeli military. The camp, a built-up residential area, is located in the evacuation zone where Israel鈥檚 military had urged Palestinian civilians to seek refuge as it focuses its military offensive on the north.

Another airstrike hit a house near a school at the Bureji refugee camp in central Gaza on Sunday, and staff at Al-Aqsa Hospital told the AP at least 13 people were killed. The camp is home to an estimated 46,000 people and was struck on Thursday as well.

Despite appeals and overseas demonstrations, Israel has continued its bombardment across Gaza, saying it is targeting Hamas and accusing it of using civilians as human shields. Critics say Israel鈥檚 strikes are often disproportionate, considering the large number of civilians killed.

in the occupied West Bank on Sunday, a day after talks with Arab foreign ministers in neighboring Jordan.

Abbas, who has had no authority in Gaza since Hamas took over in 2007, said the Palestinian Authority would only assume control of Gaza as part of a 鈥渃omprehensive political solution鈥� establishing an independent state that would also take in the West Bank and east Jerusalem, lands Israel seized in the 1967 war.

His remarks seemed to further narrow the already slim options for if Israel succeeds in toppling Hamas. The last peace talks with Israel broke down more than a decade ago, and Israel鈥檚 government is dominated by opponents of Palestinian statehood.

Earlier in his tour, Blinken met with Israeli Prime Minister Benjamin Netanyahu, who on Sunday reiterated while visiting an air force base that 鈥渢here will be .鈥� He added: 鈥淲e will just continue until we beat them, we have no alternative.鈥�

Arab leaders have called for an immediate cease-fire. But Blinken said that 鈥渨ould simply leave Hamas in place, able to regroup and repeat ,鈥� when the group launched a wide-ranging attack from Gaza into southern Israel, triggering the war.

Blinken said could be critical in protecting civilians, getting aid in and getting foreign nationals out, 鈥渨hile still enabling Israel to achieve its objective, the defeat of Hamas.鈥�

Swaths of residential neighborhoods in northern Gaza have been leveled in airstrikes. The U.N. office for humanitarian affairs says more than half the remaining residents, estimated at around 300,000, are sheltering in U.N.-run facilities. Deadly Israeli strikes have repeatedly hit and damaged those shelters.

Israeli planes once again dropped leaflets urging people to head south during a four-hour window on Sunday. Crowds of people could be seen walking down Gaza鈥檚 main north-south highway carrying baggage, even pets, or pushing wheelchairs. Others led donkey carts.

One man said they had to walk 500 meters (yards) with their hands raised while passing Israeli troops. Another described seeing bodies in damaged cars along the road. 鈥淭he children saw tanks for the first time. Oh world, have mercy on us,鈥� said one Palestinian who declined to give his name.

Another Israeli airstrike overnight struck a water well in Tal al-Zatar in northern Gaza, cutting off water for tens of thousands of people, the Hamas-run municipality in the town of Beit Lahia said in a statement.

The U.N. said about 1.5 million people in Gaza, or 70% of the population, have fled their homes. Food, water and the fuel needed for generators that power hospitals and other facilities is running out.

The war has stoked tensions across the region, with Israel and Lebanon鈥檚 Hezbollah militant group repeatedly along the border.

In the occupied West Bank, at least two Palestinians were shot dead during an Israeli arrest raid in Abu Dis, just outside of Jerusalem, according to the Palestinian Health Ministry. The military said a militant who had set up an armed cell and fired at Israeli forces was killed during the raid.

At least 150 Palestinians have been killed since the start of the war, mainly during violent protests and gun battles during arrest raids.

Thousands of Israelis protested outside Netanyahu鈥檚 official residence in Jerusalem on Saturday, urging him to resign and calling for the return of roughly 240 hostages held by Hamas. Some families are to try to make sure the hostages aren鈥檛 forgotten.

Netanyahu has refused to take responsibility for the Oct. 7 attack in southern Israel that . Ongoing Palestinian rocket fire has forced tens of thousands of people in Israel to leave their homes.

In another reflection of widespread anger in Israel, a junior government minister, Amihai Eliyahu, suggested in a radio interview Sunday that Israel could drop an atomic bomb on Gaza. He later walked back the remarks, saying they were 鈥渕etaphorical.鈥� Netanyahu issued a statement saying the minister鈥檚 comments were 鈥渘ot based in reality.鈥�

Netanyahu suspended Eliyahu from cabinet meetings, a move that has no practical effect.

Among the Palestinians killed in Gaza are , the , without providing a breakdown of civilians and fighters.

The Israeli military said 29 of its soldiers have died during the ground operation.
