Thousands of civilians flee south, as close combat reported in Gaza City

Israeli forces and Hamas militants appeared to be battling at close range in Gaza City as thousands of civilians fled south on Wednesday to avoid being trapped in the heart of the conflict.

The Israeli military said its troops had advanced into the heart of Gaza City, Hamas's main bastion and the biggest city in the seaside enclave, while the Islamist group said its fighters had inflicted heavy losses.

Hamas's armed wing on Wednesday released a video that appeared to show intense street battles alongside bombed-out buildings in Gaza City.

Israeli tanks have met heavy resistance from Hamas fighters using underground tunnels to stage ambushes, according to sources with Iran-backed Hamas and the separate Islamic Jihad militant group.

Israel struck Gaza in response to a cross-border Hamas raid on southern Israel on Oct. 7 in which gunmen killed 1,400 people, including some Canadians, and took about 240 hostages, according to Israeli tallies.

Palestinian officials in Hamas-run Gaza said 10,569 people had been killed as of Wednesday, 40 per cent of them children. Israel says 33 of its soldiers have been killed.

Tanks, fighters battling

One clip from the Hamas video released on Wednesday showed fighters running past piles of debris and stopping to fire shoulder-propelled missiles at Israeli tanks. Another showed them shooting rifles from perches behind buildings and dumpsters. Reuters was not able to authenticate the footage.

Saleh al-Arouri, an exiled Hamas commander, told Hamas-affiliated Al-Aqsa TV that Israeli forces may gain control of some areas in Gaza.

"But that will not stop the resistance's fight against soldiers and tanks. The more [Israel]spreads and expands on the ground, the deeper its losses will become," he said.

Chief Israeli military spokesperson Rear Admiral Daniel Hagari said on Wednesday combat engineers were using explosive devices to destroy Hamas's tunnel network that stretches for hundreds of kilometresbeneath Gaza. The military said it had destroyed 130 tunnel shafts so far.

Israel has blamed Hamas for civilian deaths in Gaza, saying that it is using Gazans as human shields and hiding arms and operations centres in residential areas.

Thousands of civilians flee northern Gaza on foot

WARNING: This story contains distressing images | Thousands fled northern Gaza on foot to escape heavy fighting as calls grow louder for Israel to do more to protect civilians caught in the war.

As the war entered its second month, Israeli troops took foreign reporters to the edges of Gaza City on Wednesday. Journalists saw a devastated landscape where every building within sight was scarred by battle.

Walls were blown away while bullet holes and shrapnel dotted the facades and palm trees were shredded and broken.

Lt.-Col.Ido, deputy commander of the 401st Brigade, who did not give his last name, said that by the time soldiers reached these buildings, all the families had left.

"So we know that everyone here is our enemy. We have not seen any civilians here. Only Hamas," he said, standing in a badly damaged children's bedroom that was painted pink.

Soldiers on the press tour said that beneath the family apartment were two floors of workshops used to make weapons, including drones discovered in five wooden boxes. It was not possible to verify the claim.

50,000 civilians flee north Gaza

Some 50,000 Palestinian civilians left the north on Wednesday, Hagari said, during a four-hour window of opportunity announced by Israel. He said they left "because they understand that Hamas has lost control in the north."

Thousands still remain inside the encircled north, including at Gaza City's main Al-Shifa hospital, where Um Haitham Hejela was sheltering with her young children in an improvised tent.

"There is no food, no water," she said. "When my son goes to pick up water, he queues for three or four hours in the line. They struck bakeries, we don't have bread."

The Israeli military has repeatedly told residents to evacuate the north or risk being trapped in the violence. Huge numbers of displaced people from among Gaza's 2.3 million population are already crammed into schools, hospitals and other sites in the south.

But the central and southern parts of the small, besieged Palestinian enclave also came under fire again.

Palestinian health officials said an airstrike that hit houses in Nusseirat refugee camp killed 18 people on Wednesday morning. In Khan Younis, six people, including a young girl, died in an airstrike.

"We were sitting in peace when all of a sudden an F-16 airstrike landed on a house and blew it up, the entire block, three houses next to each other," said a witness, Mohammed Abu Daqa.

International alarm is mounting over the humanitarian toll of Israel's onslaught. The level of death and suffering is "hard to fathom," UNhealth agency spokesperson Christian Lindmeier said in Geneva.

UNofficials and G7 world powers stepped up appeals for a humanitarian pause in the war to help alleviate the suffering of civilians in Gaza, where necessities including food, medicine and fuel are running out.

Negotiations mediated by Qatar, where several Hamas political leaders are based, are trying to secure the release of 10 to 15 hostages in exchange for a one- to two-day humanitarian pause in Gaza, a source briefed on the talks said on Wednesday.

Also Wednesday, the Rafah border crossing into Gaza was closeddue to an unspecified "security circumstance," but U.S. officials were working with Egypt and Israel to get it reopened, U.S. State Department deputy spokesperson Vedant Patel said.

The U.S.expects the Egypt-controlled crossing will be reopened at "regular intervals" so that aid can enter the Gaza Strip and foreign nationals can continue to depart, Patel said during a newsbriefing.

The Rafah closing leaves dozens of Canadians who had been approved to exit Gaza,unable to depart for now.
