Suze van Meegan, the Norwegian Refugee Council’s Emergency Response Leader in Gaza, has said many civilians were still stuck as Palestinians flee Rafah amid Israeli offensive.

“The city of Rafah is now comprised of three entirely different worlds: the east is an archetypal war zone, the middle is a ghost town, and the west is a congested mass of people living in deplorable conditions,” she said in a statement, according to Reuters.

UNRWA, the main United Nations agency in Gaza, estimated as of Monday that more than 800,000 people had fled Rafah since Israel began targeting the city in early May, despite international pleas for restraint.
