Around 150 tonnes of UK aid, including more than 13,000 blankets and 840 family-sized tents, has entered Gaza today and will be distributed by UNICEF, the Foreign Office has said.
It also includes almost 3,000 shelter and shelter-fixing kits, 6,000 sleeping mats and more than 3,000 dignity kits for women and girls.
A full field hospital, which the government said could be adapted according to needs on the ground, will arrive later this week.
The facility left Manchester on 5 March and can be operational in as little as 48 hours.
It will be able to treat more than 100 patients a day and usually includes a pharmacy, triage area, major injuries and resuscitation unit, as well as a maternity care tent.
The field hospital will be staffed by both local health workers and international medics, including many from the UK.
The foreign secretary also announced a further £10m in aid funding for the Occupied Palestinian Territories, bringing the total spent to over £100m this financial year.
The funding will support UN agencies on the ground to deliver lifesaving aid and provide core relief items such as tents for the most vulnerable.
Lord Cameron said: “Too many people in Gaza are suffering. No one should be without basic amenities like shelter and bedding, and everyone deserves the dignity that basic hygiene kits provide. Our largest aid delivery, combined with a new UK-funded field hospital, will save lives.
“But an immediate pause in the fighting is the only way to get aid into Gaza in the quantities desperately needed. This will also allow for the safe release of hostages.
“We could then work towards a sustainable, permanent ceasefire, without a return to destruction, fighting or loss of life.”
