KUALA LUMPUR: The United Nations Under Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator, Martin Griffiths, raised concerns about the growing humanitarian crisis in Gaza amid an Israeli blockade, leaving civilians with "no aid" for days.

Griffiths highlighted the dire situation of a region cut off from critical supplies and essential aid, as well as the desperate plight faced by Gazans.

"For three consecutive days, nothing and no one has been allowed in or out of Gaza. The closure of the crossings means no fuel. It means no trucks, no generators, no water, no electricity and no movement of people or goods.

"Civilians in Gaza are being starved and killed, and we are prevented from helping them," Griffiths wrote on the social media platform X, formerly Twitter.

He said the closure of crossings had paralysed relief efforts.

"It means no aid. Our supplies are stuck. Our teams are stuck," he wrote.

On Sunday, Israel reportedly closed the key Kerem Shalom crossing between Israel and southern Gaza where most humanitarian aid enters the Palestinian territory.

On Tuesday, the Israeli army reportedly seized and closed down the Rafah crossing between Egypt and Gaza.
