Aid trucks back in Egypt after delivering aid to Gaza.

Egyptian trucks have unloaded humanitarian aid and returned to the Egyptian side of the Rafah border crossing with Gaza, according to a CNN stringer on the ground.

The Rafah crossing was briefly opened on Saturday morning to allow the first convoy of aid trucks to enter the besieged Gaza Strip.

Humanitarian aid had been stuck in Egypt for days with Gaza plunged into a worsening crisis. The enclave is fast running out of food, water, fuel and medical supplies – all while being pounded by relentless airstrikes.
