The death toll from tank fire on a United Nations shelter in Gaza’s main southern city of Khan Younis has risen to 12, a top UN aid official has said, AFP reports.

“Twelve people have now been confirmed dead with over 75 injuries, 15 of whom are in a critical condition,” Thomas White, Gaza director of the UN agency for Palestinian refugees (UNRWA), said in a statement.

On Wednesday, two tank shells struck the UN shelter in Khan Yunis where thousands of displaced Palestinians have taken refuge, he said.

UNRWA chief Philippe Lazzarini said the bombardment was a “blatant disregard of basic rules of war”.

The compound had been clearly marked as a UN facility and its coordinates shared with Israeli authorities, he said on X.

Asked about the tank fire, the Israeli army said “a thorough review of the operations of the forces in the vicinity is underway”, adding it was examining the possibility that the strike was a “result of Hamas fire”.
