An Israeli missile has hit a convoy carrying medical supplies and fuel to an Emirati hospital in the Gaza Strip, an aid group has said.
Several people have been killed in the strike the American Near East Refugee Aid (Anera) group said on Friday.
Meanwhile Israel has claimed it opened fire after gunmen seized the convoy.
The strike killed several people employed by a transportation company that the aid group was using to bring supplies to the Emirates Red Crescent Hospital in Rafah, said Sandra Rasheed, Anera's director for the Palestinian territories.
The strike took place on Thursday on the Salah al-Din Road in the Gaza Strip and hit the convoy's first vehicle.
"The convoy, which was coordinated by Anera and approved by Israeli authorities, included an Anera employee who was fortunately unharmed," Rasheed said in a statement.
"Despite this devastating incident, our understanding is that the remaining vehicles in the convoy were able to continue and successfully deliver the aid to the hospital. We are urgently seeking further details about what happened."
Anera is expected to release more information about the attack later on Friday.
The Israeli military did not immediately respond to a request for comment on Friday from The Associated Press.
But Israeli military spokesperson Lt. Col. Avichay Adraee posted on X that "gunmen seized a car at the head of the convoy (a jeep) and began driving."
"After the seizure operation and after confirming the possibility of attacking the militants' vehicle alone, the raid was carried out, as the rest of the convoy vehicles were not harmed and reached their target according to the plan," Adraee wrote.
"The operation to target the militants removed the risk of seizing the humanitarian convoy."
He added: "The presence of armed men inside a humanitarian convoy in an uncoordinated manner makes it difficult to secure the convoys and their staff and harms the humanitarian effort."
The United Arab Emirates, which reached a diplomatic recognition deal with Israel in 2020 and has been providing aid to Gaza since the Israel-Hamas war began, did not immediately acknowledge the attack.
Israeli forces have opened fire on other aid convoys in the Gaza Strip. The World Food Program announced on Wednesday it is pausing all staff movement in Gaza until further notice over Israeli troops opening fire on one of its marked vehicles, hitting it with at least 10 rounds. The shooting came despite having received multiple clearances from Israeli authorities.
On July 23, UNICEF said two of its vehicles were hit with live ammunition while waiting at a designated holding point.
An Israeli attack in April hit three World Central Kitchen vehicles, killing seven food aid workers.
Britons John Chapman, 57, James Henderson, 33, and James Kirby, 47, died with four World Central Kitchen colleagues when the three vehicles they were using to deliver food were hit in a triple drone strike by the Israel Defence Forces.
All three Brits were part of the aid organisation’s security team with Mr Henderson, a former Royal Marine, due to leave Gaza that day. Mr Chapman, from Poole, Dorset, is understood to have been a former member of Britain’s special forces.
