The World Health Organisation (WHO) announced that, due to a lack of security assurances, it was forced to postpone a mission to deliver medical supplies to northern Gaza on Sunday. Since December 26, WHO said, it had been forced to postpone four times a scheduled expedition to deliver critically needed medical supplies to Al-Awda Hospital and the primary pharmacy in northern Gaza. Tedros Adhanom Ghebreyesus, the director-general of WHO, expressed his dismay at the extent of the devastation and health needs in northern Gaza. “Further delays will lead to more death and suffering for far too many people,” he wrote in a post on X. As part of a diplomatic drive, US Secretary of State Antony Blinken continued his meetings with Arab leaders on Monday.
