The United Nations is looking for ways to evacuate Al-Shifa hospital in Gaza but options are limited by security and logistical constraints, a senior World Health Organisation (WHO) official said.

One obstacle is that the Palestinian Red Crescent lacks sufficient fuel for its ambulances within Gaza to evacuate patients, WHO regional emergencies director Rick Brennan told Reuters.

Egypt was open to having its ambulances cross into Gaza to help evacuate people as long as security guarantees and safe passage could be provided, he said.
