The World Health Organization confirmed that there was an extermination of entire families and the destruction of infrastructure in the Gaza Strip, while the Government Information Office in Gaza on Saturday criticized the departure of the United Nations Relief and Works Agency for Palestine Refugees (UNRWA) to the south of the Strip.

The organization's regional director, Tedros Adhanom Ghebreyesus, in an interview with Al Jazeera, appealed to the international community to open the crossings with Gaza immediately to bring in aid, saying that there is coordination with the Egyptian authorities to open the Rafah crossing.

Ghebreyesus pointed out that the evacuation of seriously ill patients from Gaza hospitals is tantamount to a death certificate after Israel asked some hospitals in the Strip to evacuate.

The World Health Organization confirmed that 13 health facilities had been attacked in the Gaza Strip since the beginning of the bombing, and indicated that the stock of medical supplies had ended.

In a related context, the Government Information Office in Gaza considered that UNRWA had abandoned its duty towards the displaced after the Israeli warning yesterday, Friday, to deport the people of northern Gaza within 24 hours.

The United Nations announced yesterday that UNRWA will move its operations headquarters and foreign employees to the southern Gaza Strip, to continue its relief operations and support for refugees, after it warned of the devastating humanitarian consequences of the Israeli ultimatum and demanded its cancellation.

UNRWA had called on Israel to protect civilians in its facilities in the northern Gaza Strip, amid the continued Israeli aggression against Gaza and the prevention of the entry of water, food and humanitarian aid since October 7, following the “Al-Aqsa Flood” operation launched by the Palestinian resistance.

UNRWA advisor in Gaza, Adnan Abu Hasna, told Al Jazeera that huge crowds of citizens are sleeping in the streets because there are no places to shelter them, adding that their headquarters are no longer able to accommodate the numbers of displaced people.

UN Human Rights Rapporteur Francesca Albanese warned that the great danger we are witnessing in Gaza after the Israeli warning may be a repetition of the 1948 catastrophe and the 1967 catastrophe, but on a larger scale.

United Nations High Commissioner Filippo Grandi also called on Israel to respect international law and allow the organization to deliver humanitarian aid to Gaza, especially since hospitals in the Strip are unable to accommodate more injured people.

Doctors Without Borders called on Israel to stop the indiscriminate bloodshed in the Gaza Strip, withdraw the evacuation warning, and protect health facilities and civilians. Israel bombed a convoy of displaced people yesterday, Friday, which led to the death of 70 Palestinians and the injury of more than 150 others.
