A first group of injured evacuees from Gaza crossed into Egypt on Wednesday under a Qatari-mediated deal, Egyptian media and a source at the border said, as Israeli forces pressed their battle against Hamas militants in the Palestinian enclave.

The evacuees were driven in ambulances through the Rafah border crossing. Under the deal reached between Egypt, Israel and Hamas, a number of foreigners and critically wounded people will be allowed to leave the besieged territory.

Qatar has mediated an agreement between Egypt, Israel and Hamas, in coordination with the U.S., which will allow limited evacuations from besieged Gaza, a source briefed on deal told Reuters on Wednesday.

The agreement would allow foreign passport holders and some critically injured people to leave through the Rafah border crossing between Egypt and Gaza, though there is no timeline for how long it will remain open for evacuation, the source added.

The deal is not linked to other issues under negotiation such as hostages held by Hamas, the Palestinian Islamist group that governs Gaza, or pauses designed to ease a humanitarian crisis in the enclave which is suffering from food, water, fuel, and medical shortages, the source said.

Israel sent its forces into Gaza following weeks of air bombardments in retaliation for a major attack by Iran-backed Hamas on Oct 7.

Reuters news agency, citing Israeli army, is reporting that nine Israeli soldiers have been killed in Gaza.

Israeli airstrikes hit a densely populated refugee camp in the Gaza Strip, killing at least 50 Palestinians and a Hamas commander, and medics struggled to treat the casualties in the enclave where food, fuel and basic supplies are running scarce.

The Israeli military said 11 soldiers were also killed in fighting in Gaza on Tuesday, the biggest one-day loss for the armed forces since Hamas gunmen attacked southern Israel on Oct. 7, killing about 300 soldiers and some 1,100 civilians.
