NEW YORK CITY: The Rafah crossing on the border between Gaza and Egypt opened for a fourth consecutive day on Thursday, allowing a limited number of people to pass through.

However, the UN voiced concerns about reported mistreatment of Palestinians returning to the war-ravaged enclave.

The UN’s Office for the Coordination of Humanitarian Affairs also said reports continue across civilian areas in Gaza of airstrikes, gunfire and shelling, resulting in casualties and damage to infrastructure.

And Israeli forces on Wednesday demolished Jabalya Preparatory Boys’ School in northern Gaza, OCHA said. Run by the UN Relief and Works Agency for Palestine Refugees, it was the last remaining school in a compound of six. Its destruction means the entire educational complex has been razed to the ground.

A limited flow of people were allowed to use the Rafah crossing, Gaza’s main physical connection to the outside world, for four days in a row since it reopened on Monday, OCHA said. Only 98 returnees were received by UN teams inside Gaza between Monday and Thursday, it added, and the crossing remains closed on Fridays.
