The World Health Organization canceled another medical aid mission scheduled for the Gaza Strip on Wednesday due to security concerns, the sixth such cancellation in two weeks.

The Director-General of the World Health Organization, Tedros Adhanom Ghebreyesus, said that the canceled mission is the sixth mission to northern Gaza that the organization has canceled, due to the failure to approve visit requests, in addition to the failure to provide security assurances since the last visit on December 26.

“Intensive bombing, movement restrictions, fuel shortages and communications blackouts make it impossible for the World Health Organization and our partners to reach those in need,” he said in a virtual press conference from Geneva.

He called on "Israel to approve requests from the World Health Organization and other partners to provide humanitarian aid."

Earlier, the Director-General of the World Health Organization warned on Wednesday that Gazans face “grave danger,” speaking of the spread of acute hunger and despair throughout the Strip, which was devastated by the Israeli war.
