The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) says Israel’s multiple evacuation orders have disrupted health services in Gaza, Al Jazeera reports.

“The distance of these [evacuation] orders is one kilometre or less from four key hospitals: Nasser Medical Complex, Al-Amal and Kuwaiti Palestine Red Crescent Society (PRCS) hospitals, and Al Aqsa Hospital, hindering people’s access to healthcare,” OCHA said in its latest update on Israel’s onslaught on Gaza.

The UN organisation added that the success of an upcoming polio vaccination campaign hinges on both sides committing to a humanitarian pause for at least seven days for each round of vaccinations.

“Without this, insecurity will prevent the campaign from being fully implemented and the risk of poliovirus spreading across the Strip and beyond remains high,” OCHA said.
