A deadly airstrike has killed at least 35 people inside western Rafah, near the UNRWA logistics base in Tal Al-Sultan, according to officials at the Hamas-run Gaza Ministry of Health.

Numerous individuals remain stuck in a fire that resulted from the airstrike and in the tents destroyed by the bombardment.

The Israeli Defense Forces (IDF) confirmed the airstrike to ABC News in a statement on Sunday and acknowledged that civilians were harmed as a result of the strike.

"A short while ago, an IDF aircraft struck a Hamas compound in Rafah in which significant Hamas terrorists were operating. The strike was carried out against legitimate targets under international law, using through the use of precise munitions and on the basis of precise intelligence that indicated Hamas' use of the area," the IDF said.

"The IDF is aware of reports indicating that as a result of the strike and fire that was ignited several civilians in the area were harmed," the IDF continued, adding, "The incident is under review."

An Egyptian border guard was killed in a shooting in the Rafah border area with Gaza, Egypt’s military spokesman said in a statement on Monday.

"The Egyptian armed forces, through the competent authorities, are investigating a shooting incident in the Rafah border area which led to the martyrdom of one of the security personnel on duty," the statement said.

The Israeli military had earlier reported an exchange of fire on the Egyptian border and said it was discussing the incident with Egypt.

“A few hours ago (Monday), a shooting incident occurred on the Egyptian border. The incident is under review and discussions are being held with the Egyptians,” the IDF said.

Initial investigations into an incident that killed an Egyptian border guard indicate the incident occurred while there was an exchange of fire between Israeli forces and "the Palestinian resistance," an Egyptian security source told Egypt’s state-affiliated Al Qahera News TV on Monday.

In October 2023, weeks after the war started, Israel said one of its military tanks mistakenly fired at an Egyptian position near the border with Gaza. Egypt said at the time that several army personnel were slightly injured.

Tensions between Egypt and Israel have escalated after Israeli forces earlier this month seized control of the Rafah border crossing, a key entry point for humanitarian aid. Egypt said it would not reopen its side of the crossing unless it is operated by Palestinians and accused Israel of preventing aid deliveries.
