The US has carried out its first airdrop of aid for Gaza, with more than 30,000 meals parachuted in by three military planes.

The operation was carried out in conjunction with the Jordanian Air Force, the US Central Command said.

US officials say the drop was the first of many announced by President Joe Biden on Friday.

He promised to step up aid to Gaza after the death of over 100 people seeking aid from a convoy on Thursday.

C-130s dropped more than 38,000 meals along the coastline of Gaza, US Central Command said in a statement.

"These airdrops are part of a sustained effort to get more aid into Gaza, including by expanding the flow of aid through land corridors and routes," it added.

Other countries including Britain, France, Egypt and Jordan have previously airdropped aid into Gaza, but this is the first by the US.

In his statement on Friday, President Biden said the US would "insist that Israel facilitate more trucks and more routes to get more and more people the help they need".

US officials say Israel is supportive of the mission, which is being carefully planned to ensure the safety of those on the ground.

Aid agencies have said that airdrops are an inefficient, expensive and complex way of delivering supplies.

The fact that the US has opted for this method highlights the severity of the humanitarian crisis and the difficulty of getting aid by road to Gazan civilians.

In Thursday's incident, 112 people were killed and more than 760 injured as they crowded around aid lorries on the southwestern edge of Gaza City.

Hamas accused Israel of firing at civilians, but Israel said most died in a crush after it fired warning shots.
