Hamas on Thursday called for an end to airdrops of aid after two Palestinians were killed in northern Gaza when an aid pallet crashed into a warehouse after its parachute failed to open.

Several countries, including the United States, Britain and France, have resorted to regular aid airdrops in northern Gaza, where humanitarian agencies have warned of a looming famine.

On Tuesday, two people died when an aid parachute fell on the roof of a warehouse where residents had gathered to collect relief supplies.

The latest fatalities take to at least 21 the number of people killed when airdrops of aid have gone disastrously wrong, according to the Hamas authorities.

“We reiterate that airdrops pose a real danger to the lives of citizens and do not provide a real solution to alleviate the food crisis plaguing northern Gaza,” Salama Marouf, head of the government’s media office in Gaza, said in a statement.

“We call for an immediate halt to the delivery of aid in this ineffective and erroneous manner, and we call for the full activation of the land crossings to deliver humanitarian aid to northern Gaza.”
