More patients, including premature babies, have reportedly died in Gaza City's Al-Shifa hospital which has gone three days without electricity amid intensifying Israeli military operations, making a ceasefire more urgent than ever, UN humanitarians have said.

The UN's health agency WHO said on Sunday night that according to the Gaza health authorities, 37 premature babies at the hospital were relocated over the weekend to an operating room without their incubators, with health workers trying to heat the room. According to the latest media reports on Monday, six babies at Al-Shifa have died.
