The UN humanitarian chief has denounced the ongoing Israeli genocidal war against the besieged Gaza Strip as a ‘betrayal of humanity.’

Martin Griffiths, the world body's under-secretary-general for humanitarian affairs and emergency relief, made the remarks in a statement on Saturday.

"Each day, this war claims more civilian victims," he said, adding, "Every second that it continues to sow the seeds of a future so deeply obscured by this relentless conflict."

Griffiths lamented "the unconscionable prospect of further escalation in Gaza, where no one is safe and there is nowhere safe to go."

The UN official called for a "collective determination that there be a reckoning for" this brutal campaign of bloodshed and destruction.

Griffiths, meanwhile, noted that "an already fragile aid operation continues to be undermined by bombardments, insecurity, and denials of access."

The Israeli regime launched the war on October 7 last year following Operation al-Aqsa Storm, a surprise retaliatory operation by Gaza's Resistance movements that came in response to decades of oppression and bloodshed by the regime against Palestinians.

So far during the war, Tel Aviv has killed around 33,200 Palestinians, most of them women, children, and adolescents, and injured more than 75,800 others.

Concomitantly with the military campaign, the regime has been enforcing a near-total siege on Gaza, which has reduced the flow of foodstuffs, medicine, electricity, and water into the Palestinian territory into a trickle.

The United Nations has warned that in the absence of any changes in the course of the warfare, the coastal sliver was on course to experience all-out famine.
