The World Health Organisation (WHO) cancelled another planned medical aid mission to Gaza on Wednesday over security concerns, the sixth such cancellation in two weeks.
WHO Director-General Tedros Adhanom Ghebreyesus said it was the sixth mission to northern Gaza cancelled by the UN agency because requests to visit had not been approved or assurances over security provided since its last visit, on December 26.
"Intense bombardment, restrictions on movement, fuel shortage and interrupted communications make it impossible for WHO and our partners to reach those in need," he told a virtual press conference from Geneva.
"We call on Israel to approve requests by WHO and other partners to deliver humanitarian aid," he added.
The Israeli offensive launched in the wake of a rampage by Hamas in southern Israel on October 7 has displaced most of Gaza's 2.3 million population, left many homes and civilian infrastructure in ruins, and caused acute shortages of food, water and medicine.
The WHO said on Wednesday only 15 hospitals in Gaza remain functional, even partially.
