A Palestinian father mourns his son durin the funeral in Rifah.

Returning from an eight-day mission to the south of the besieged Palestinian territory, the deputy director of Handicap International - Humanity & Inclusion (HI) said he was still "stunned." He told AFP he had never seen such a combination of "bombardment of an extremely densely populated and closed-off area, and a near-complete lack of access for humanitarian aid."

Deliveries into the Gaza Strip have been reduced substantially since the start of the latest Israeli military campaign in the territory.

The United Nations has warned of looming famine, and calls have grown for the Israeli authorities to let in and ensure the safe delivery of desperately needed aid waiting in lorries on the Egyptian side of the border.

"I saw kilometres of trucks queueing on four lanes, all waiting to get into Gaza," said 61-year-old Delomier.

Foreign governments have scrambled to parachute in pallets of supplies from airplanes in recent weeks, but aid workers have warned they only cover a tiny fraction of needs and the method is hugely expensive.

"Planes fly over to drop a few pallets, whereas just behind (the border) there are kilometres of pallets waiting that could just be let in," he said, incensed.

'Mousetrap'

The aid worker, who started his career in Bosnia and Herzegovina in the 1990s, said what he witnessed in Gaza's southern city of Rafah was incomparable.

About 1.5 million of the territory's 2.4 million residents have crammed into Rafah, squashed up against the closed Egyptian border, most after fleeing Israeli bombardment on other parts of the territory.

When food is available, restrictions make it extremely expensive. And Israel air strikes have repeatedly hit the city.

Gazans, Delomier said, were caught in a "mousetrap, with only a trickle of aid — whereas all that is needed is right there next door — and bombardment."

He said people sometimes tried to compare the situation in Gaza with the 1994 Rwanda genocide, the Syrian civil war since 2011, or even the ongoing conflict in Yemen. But the crisis in Gaza "is the worst I have ever seen," he said.

'Outraged'

Delomier said he worked in Rafah with the constant buzz of Israeli drones overhead. "There was artillery fire and then, especially the constant buzzing of drones. The whole time, day and night, a permanent background noise," he said. Further north, conditions are even more dire and some residents have been reduced to eating animal fodder.

The United Nations on Tuesday called on the international community to "flood" Gaza with aid, after reports children are dying of starvation there.

Delomier said he was still reeling from what he saw of the situation. "In fact, I am outraged," he said.
