The border crossing between Egypt and Gaza opened on Saturday to let a trickle of desperately needed aid into the besieged Palestinian territory for the first time since Israel sealed it off.
Just 20 trucks were allowed in, an amount that aid workers said was insufficient to address the unprecedented humanitarian crisis in Gaza.
It comes as Israel says it plans to step up its attacks on the Gaza Strip starting on Saturday as preparation for the next stage of its war on Hamas.
More than 200 trucks carrying roughly 2700 tonnes of aid have been positioned near the crossing for days.
Gaza’s 2.3 million Palestinians, half of whom have fled their homes, are rationing food and drinking dirty water.
Hospitals say they are running low on medical supplies and fuel for emergency generators amid a territory-wide power blackout.
Five hospitals have stopped functioning because of fuel shortages and bombing damage, the Hamas-run Health Ministry said.
