Israeli forces bombed wide areas of the Gaza Strip on Sunday, killing and wounding dozens of Palestinians, as civilians in the besieged territory sought shelter in an ever-shrinking area of the south.
The Hamas group said its fighters clashed with Israeli troops about 2 km (1 mile) from the southern city of Khan Younis. Residents, many of whom had moved there to flee earlier attacks, said they could hear tank fire and feared a new Israeli ground offensive was building.
The Israeli military earlier ordered people to evacuate some areas in and near the city, but made no announcement of any new southern ground assault.
Fuelling fears the conflict could spread to destabilise the region, Yemen's Iran-allied Houthi movement said it attacked two Israeli ships in the Red Sea with an armed drone and a missile on Sunday, in a move to stand with the Palestinians.
The Pentagon also said it was aware of reports of an attack on an American warship, the USS Carney, without going into detail. There was no independent confirmation from Israel or the U.S. of the attacks or what damage they caused, if any.
The Jabalia refugee camp in the north of Hamas-ruled Gaza was among the sites reported hit from the air. A Gazan health ministry spokesperson said several people were killed by an Israeli air strike.
Footage obtained by Reuters showed a boy covered in grey dust, sitting weeping amid crumbled cement and rubble from collapsed buildings.
"My father was martyred," he cried in a hoarse voice. A girl in a pink sweatshirt, also coated with dust, stood between piles of rubble.
Bombardments from war planes and artillery were also concentrated on Khan Younis and Rafah, another city in Gaza's south, residents said, and hospitals were struggling to cope with the flow of wounded.
Israel's government spokesperson, Eylon Levy, said the military had struck more than 400 targets over the weekend "including extensive aerial attacks in the Khan Younis area" and had also killed Hamas militants and destroyed their infrastructure" in Beit Lahiya in the north.
There was no immediate comment on the reports of specific attacks.
The renewed warfare followed the end on Friday of a seven-day pause in the fighting between Israeli forces and Hamas militants which had allowed an exchange of Israeli hostages and Palestinian prisoners.
The violence took place despite calls from the United States -- Israel's closest ally -- for Israel to limit harm to Palestinian civilians in the new phase of its offensive, focused on the south.
More than 15,523 people have been killed, according to Gaza's health ministry, in nearly two months of warfare that broke out after a Hamas cross-border raid on southern Israel on Oct. 7 in which 1,200 Israelis were killed and around 240 taken hostage.
Israel has vowed to annihilate Hamas. The Iranian-backed group is sworn to Israel's destruction. The initial Hamas attack and the ensuing war amount to the bloodiest episode in the decades-old wider Israel-Palestinian conflict.
Ground Offensive Feared
Gaza residents said on Sunday they feared an Israeli ground offensive on the southern areas was imminent. Tanks had cut off the road between Khan Younis and Deir Al-Balah in central Gaza, effectively dividing the Gaza Strip into three areas, they said.
The Israeli military ordered Palestinians to evacuate several areas in and around Khan Younis. It posted a map highlighting shelters they should go to west of Khan Younis and south towards Rafah, on the border with Egypt.
Many residents started packing, but said that areas they had been told to go to were themselves coming under attack.
Nabil Al-Ghandour told Reuters he and his family would leave Khan Younis for Rafah later on Sunday, their fifth move in search of safety since the conflict started.
"We can't see any safe areas," he said. "But we move because what can we do? We have children and all night there's shelling."
Later on Sunday, a Gazan health ministry official said that seven people were killed in an air strike on a house in Rafah. The Israeli military did not immediately respond to a request for comment.
U.N. officials and residents said it was difficult to heed Israeli evacuation orders because of patchy internet access and no regular supply of electricity.
Israeli Prime Minister Benjamin Netanyahu said on Saturday that Israel was coordinating with the U.S. and international organisations to define "safe areas" for Gaza civilians.
Tunnels Hit
The Israeli military said on Sunday its war planes and helicopters had struck Hamas targets including tunnel shafts, command centres and weapons storage facilities. Naval forces had hit Hamas vessels on the coast, it said.
The military declined to give figures on the number of air strikes carried out.
Hamas said it targeted the coastal Israeli city of Tel Aviv with a rocket barrage. There were no reports of damage, but paramedics said one man was treated for a shrapnel injury.
A synagogue in the southern Israeli city of Sderot was damaged on Sunday by what Israeli media said was a rocket was fired from Gaza. Local emergency services reported no casualties.
On another front, Israeli forces and Hezbollah militants traded fire across the Israel-Lebanon border and Israel said several of its soldiers were wounded when an anti-tank missile fired from Lebanon hit a vehicle in the Beit Hillel area of northern Israel.
Reuters could not independently verify the accounts.
About 1.8 million people, or 80% of Gaza's population, have fled their homes since Oct. 7, the United Nations says.
More than 400,000 displaced people have sought shelter in Rafah and nearly 300,000 have taken shelter in Khan Younis, according to the U.N. humanitarian office.
