Fuel shortages are pushing hospitals in Gaza to the “brink of collapse”, with people facing dehydration, disease and starvation, the charity ActionAid has warned.

Dr Mohammad Salha, acting director of al-Awda hospital in northern Gaza, said a lot of services at the hospital were affected by the lack of fuel. In a voice note message, he told ActionAid:

The [World Health Organization] [was] providing fuel and medical supplies and medication.[But] from 22 April [until] now they are not providing because the Israeli [military] refused to [let] the fuel and medical supplies [enter]. So, [for] more than 50 days the hospital is without fuel and medical supplies and the fuel that they are bringing is only [enough] for two weeks.

[As a result] we are decreasing our intervention and we are not running the big generators. We are running the small generators only to recharge the batteries. And [on this] we are doing the surgeries related to life saving.”

Our laboratory is also affected. We can’t do many analyses, related to orthopedic analysis [and] we are dealing with many patients … 70% of people who [are] affected from the Israeli aggression need orthopedic surgery.”

Fuel is absolutely crucial to keep the infrastructure needed to sustain life operational in Gaza. It is shocking that hospitals are having to reduce their services due to shortages and that life-saving equipment could be forced out of action.

The trickle of aid currently entering Gaza is nowhere near enough to meet the enormous and ever-growing humanitarian need.

Osama Hamdan’s comments signal group’s position on ceasefire proposal remains largely unchanged

A senior Hamas official has said the group does not know how many of the Israeli hostages it is holding in Gaza are still alive, as Israeli and Hamas sources set out positions that could undermine the possibility of an imminent ceasefire deal.

The Lebanon-based Hamas official Osama Hamdan said in an interview with CNN that “no one has any idea” how many of the remaining 120 hostages captured on 7 October last year were still alive, amid Israeli estimates that at least a third had died in captivity or were killed when seized.

At least 236 Palestinians were killed in Israel’s raid to free hostages Saturday, Gaza health officials have told the Washington Post.

At al-Awda Hospital, where victims were transported, there were 142 bodies, hospital director Marwan Abu Nasser told the US newspaper. Al-Aqsa Martyrs hospital spokesman Khalil al-Degran said over the weekend that the hospital had at least 94 bodies. Hundreds more are believed to be wounded.
