UN Secretary-General Antonio Guterres has raised alarm bells over the dire humanitarian situation in the blockaded Gaza Strip, saying people are not only dying from bombs but also from lack of life-saving food and medicine.

Guterres reiterated his demand for an urgent humanitarian cease-fire and the immediate and unconditional release of all hostages in the Gaza Strip.

"I will not relent in my call for an immediate humanitarian ceasefire and the immediate & unconditional release of all hostages," Guterres wrote on X.

Highlighting the humanitarian crisis in Gaza which has been under an onslaught of Israeli attacks since Oct. 7, he said: "People in Gaza are dying not only from bombs and bullets, but from lack of food & clean water, and hospitals without power & medicine."
