World Health Organisation (WHO) spokesperson Margaret Harris has warned that hospitals in Gaza only have fuel to operate for the next two to three days as Israel continues to block the Rafah crossing, Al Jazeera reports.

Harris said the entry of humanitarian and medical supplies to Gaza has “stopped completely”.

“We were expecting to have fuel delivered today. We don’t have it,” she told Al Jazeera. “So we’ve had to suspend some of our activities to the north because we want to reserve that fuel for the hospitals to ensure that they can continue their life-saving work.”

She warned that the outbreak of diseases could become a “death sentence” for malnourished children across Gaza.

“We, as humans, must not let this continue. Please, please have a ceasefire now,” Harris said.
