Less than a kilometre from Gaza, pallets of food, fuel, water, and medicine are among the hundreds of tonnes of lifesaving aid packed into a long convoy of trucks idling on the Egyptian side of the Rafah border crossing, as drivers await Israel's green light so they can reach 2.3 million besieged Palestinians caught in the crossfire of the ongoing war.

As humanitarians continued to echo the UN Secretary-General's urgent calls on Israel to open a safe aid delivery corridor, Gaza will soon run out of basic supplies, according to UN agencies on the ground, who raised alarms about a looming unprecedented humanitarian catastrophe.
