GENEVA -- UN human rights chief Volker Turk on Tuesday said that the latest intensive attacks launched by Israel on Gaza have "added more misery to the suffering of hungry Palestinians."

Turk, who is the UN High Commissioner for Human Rights, said in a statement that the Israeli airstrikes and ground operations will invariably lead to further civilian deaths and destruction of civilian infrastructure.

The Israeli military on Monday launched attacks on parts of Deir al-Balah in central Gaza in an expanded offensive following a warning issued the previous day ordering residents to evacuate in anticipation of immediate action.

Citing the concentration of civilians in the area and the means of warfare employed by Israel, Turk said the risks of unlawful killings and other serious violations of international humanitarian law are extremely high.

"Homes have already been destroyed, and thousands have been forced to flee the area again," said Turk.

He warned Israel that permanently displacing people living under its occupation would amount to unlawful transfer, which is a war crime, and in certain circumstances, may also amount to a crime against humanity.

Turk noted that the area targeted by the Israeli attacks is also home to several humanitarian organizations, including clinics, other medical facilities, shelters, a community kitchen, guesthouses, warehouses and other critical infrastructure.

He urged Israel, as the occupying power, to ensure food, medical and other supplies are provided for the population and immediately and unconditionally allow humanitarian aid to enter and be distributed to all those who are in need.

"Instead of launching round upon round of new military attacks, there must be an immediate end to the killings, destruction and the wide scale violations of international law," said Turk.
