Israeli forces shelled tent camps for displaced Palestinians north of Gaza's southern city of Rafah on Friday, killing at least 25 people and wounding another 50, according to the territory's Heath Ministry and emergency workers. It was the latest deadly attack in the tiny Palestinian enclave where hundreds of thousands have fled fighting between Israel and Hamas.

According to Ahmed Radwan, a spokesperson for the Civil Defense first responders in Rafah, witnesses told rescue workers about the shelling at two locations in a coastal area that has become filled with tents. The Health Ministry reported the number of people killed and wounded in the attacks.

The locations of the attacks provided by Civil Defense were just outside an Israeli-designated safe zone.

The Israeli military said the episode was under review but that “there is no indication that a strike was carried out by the IDF" in the area, using an acronym for the Israeli forces. It also did not offer details on any other strikes or what their intended targets might have been.

Israel has previously bombed locations in the vicinity of the “humanitarian zone” in Muwasi, a rural area on the Mediterranean coast that has filled with sprawling tent camps in recent months.

Witnesses whose relatives were killed in one of the bombardments near a Red Cross field hospital told The Associated Press that Israeli forces fired a second volley that killed people who had come out of their tents.

The attack began with a munition that only made a loud bang and bright flash, said Mona Ashour, who lost her husband after he went to investigate what was happening.

“We were in our tent, and they hit with a sound bomb' near the Red Cross tents, and then my husband came out at the first sound,” Ashour said, holding back tears while clutching a young girl outside Nasser Hospital in nearby Khan Younis.

“And then they hit with the second one, which was a little closer to the entrance of the Red Cross,” she said.

Hasan al-Najjar said his sons were killed helping people who panicked after the first strike.

"My two sons went after they heard the women and children screaming," he said at the hospital. "They went to save the women, and they struck with the second projectile, and my sons were martyred. They struck the place twice.”

The strikes came as Israel pushed ahead with its military operation in Rafah, where over a million Palestinians had sought refuge from fighting elsewhere in Gaza. Most have now fled Rafah, but the United Nations says no place in Gaza is safe and humanitarian conditions are dire as families shelter in tents and cramped apartments without adequate food, water, or medical supplies.

Friday's strikes took place less than a month after an Israeli bombing triggered a deadly fire that tore through a camp for displaced Palestinians in southern Gaza, drawing widespread international outrage — including from some of Israel's closest allies — over the military's expanding offensive into Rafah.

Israel says it is targeting Hamas fighters and infrastructure and that it tries to minimise civilian deaths. It blames the large number of civilian casualties on militants and says it's because they operate among the population.

With Israel's war against Hamas now in its ninth month, international criticism is growing over Israel's campaign of systematic destruction in Gaza, at a huge cost in civilian lives. The top United Nations court has concluded there is a “plausible risk of genocide” in Gaza — a charge Israel strongly denies.

Israeli ground offensives and bombardments have killed more than 37,100 people in Gaza, according to the territory's Health Ministry, which does not distinguish between combatants and civilians in its count.

Israel launched the war after Hamas' Oct 7 attack, in which militants stormed into southern Israel, killed some 1,200 people — mostly civilians — and abducted about 250.
