LONDON: A British charity has urged the UK government to evacuate 21 critically ill children currently in a hospital in northern Gaza, Sky News reported. The Kamal Aswan Hospital is besieged by Israeli forces and was recently raided by troops, who detained staff and left the facility with only two doctors to care for more than 150 patients. It was also targeted by an Israeli airstrike on Thursday. Its supplies are reportedly running low and many of its facilities are no longer operational.
