The Palestinian Civil Defence reported that at least 40 people were killed in the Israeli attack in Rafah. 

The Palestinian Red Crescent said on Sunday that an Israeli airstrike shelled a designated humanitarian aid site near the southern Gaza Strip city of Rafah. 

The Red Crescent said in a statement on its X account that tents for displaced people located near the United Nations centre northwest of Rafah were targeted. 

On Monday, Egypt condemned the "deliberate shelling of displaced persons' tents" by Israeli forces.

In Cairo, the Egyptian Foreign Ministry issued a statement calling on Israel to "implement the measures taken by the International Court of Justice (ICJ) on the immediate cessation of military operations" in the Palestinian town of Rafah on the border with Egypt.

Francesca Albanese, the Special Rapporteur on the Palestinian Territories, appointed by the UN Human Rights Council but not speaking on behalf of the organisation, spoke of "even more horrors in the Gaza ghetto". "This cruelty and flagrant disregard for international law is unacceptable," Albanese wrote on her X account.

The international non-governmental organisation Doctors Without Borders said on its X account that it was "appalled" by the attack, which "once again shows that there is no safe place" in Gaza. The organisation said a medical centre it runs in the area had received "dozens of wounded and more than 15 dead".
