Israel Says Its Military Has Encircled Khan Younis in Gaza

Israel’s military said on Tuesday that it had encircled the city of Khan Younis in southern Gaza, part of a push that has resulted in intense fighting and bombardments in an area packed with civilians who have fled their homes in other parts of the territory.

The Israeli military described the area as a “significant stronghold” of Hamas’s Khan Younis brigade and said that it had killed dozens of Hamas fighters over the previous 24 hours. The military’s claims could not be independently verified.

Israeli forces “targeted terrorist cells carrying R.P.G.s near the troops, those launching anti-tank missiles, and terror operatives who had rigged compounds with explosives,” the military said in a statement, referring to rocket-propelled grenade launchers. “Ready-to-launch rockets, military compounds, shafts, and numerous weapons were located during the activity,” the military added.

The fighting has involved heavy exchanges of gunfire and a surge of Israeli tanks and troops into areas around the city’s hospitals. Displaced civilians in the area say they have no safe place to go.

Eman Jawad, who is sheltering in an industrial zone in Khan Younis, said that Israeli forces surrounded her shelter on Sunday night and heavy clashes broke out with Hamas fighters. She said the fighting was so close that several tents housing displaced people went up in flames.

“We are trapped,” Ms. Jawad said in a voice message on Monday. “There are snipers on the streets and we are not allowed to leave the industrial zone.”

Rasha Ahmad, 31, said she was not able to find a safe route to evacuate from Khan Younis to Rafah, Gaza’s southernmost district, on Monday because “Israeli tanks were everywhere.” But despite the risk, she and many others decided they had no choice but to make the nearly four-hour journey on foot because Khan Younis was no longer safe, Ms. Ahmad said.

“Five men were shot by a sniper in front of my eyes,” she said in one of a series of frazzled voice messages on Monday. “I’m sure they are dead — they were left to bleed on the ground.” Her account could not be independently confirmed.

Hisham Mhanna, a spokesman for the International Committee of the Red Cross, who is in the Rafah area — where many Gazans have fled — described seeing streams of people leaving Khan Younis along a coastal road well past midnight into Tuesday.

In the morning, he said, many people were unpacking the few belongings they had managed to keep with them through multiple displacements and searching for space to set up makeshift tents. The area had experienced a roughly fourfold increase in population even before the latest escalations in Khan Younis.

“Two months ago, this area was more or less desert,” Mr. Mhanna said. “Now you can barely find an empty spot.”

A spokeswoman for the Palestinian Red Crescent Society said on Monday that Israeli forces had essentially besieged the entire Khan Younis district. The organization said that the presence of Israeli troops near Al-Amal Hospital, which it operates, meant that ambulances could not reach the injured in Khan Younis and that anyone moving in the area was being fired upon.

The Israeli military said on Monday that it was aware of sensitive sites in the Khan Younis area, including several hospitals, but that Hamas “exploits the civilian population” and has used medical facilities in its operations, including an attack launched last week from Nasser Hospital. It said areas occupied by civilians had been marked and the soldiers involved would use their experience to “mitigate harm to uninvolved individuals.”

The health authorities in Gaza have said in recent days that more than 25,000 people there have been killed since Israel began its campaign to defeat Hamas, adding that more than 63,000 others had been injured.

Prime Minister Benjamin Netanyahu of Israel began the campaign after Hamas attacked the country on Oct. 7, killing more than 1,200 people and taking around 240 people hostage, according to the Israeli authorities. More than 100 of those hostages remain in captivity.

Israeli forces, using thousands of airstrikes and a ground invasion, largely secured military control of northern Gaza before pushing south. The United Nations said this month that more than 60 percent of homes in Gaza had been damaged or destroyed during the campaign, while almost all of the strip’s 2.2 million people have been displaced from their homes.
