A UN agency has warned dwindling fuel supplies could force it to stop aid operations in war-riven Gaza, as calls mount for a humanitarian “pause” in fighting, AFP reports.

After 18 days of withering Israeli air strikes and a near-total land, sea and air blockade of the Palestinian territory, the UN agency for Palestinian refugees (UNRWA) warned operations were at breaking point.

“If we do not get fuel urgently, we will be forced to halt our operations in the Gaza Strip,” said the UN agency, which provides aid to 600,000 displaced Gazans.
