The United Nations’ humanitarian agency OCHA has said it was deeply concerned about the escalation of hostilities in Gaza’s Khan Younis, which have pushed more and more people south in recent days, AFP reports.

“Most are living in makeshift structures, tents or out in the open,” OCHA spokesman Jens Laerke said during a briefing in Geneva.

“Rafah is a pressure cooker of despair, and we fear for what comes next.”
