The Gaza strip, often called an open-air prison, has few exit and entry points. The Rafah crossing is one of the three.
Rafah crossing is the southernmost post in Gaza and opens up in Egypt. The Rafah crossing is the only one majorly used by civilians.
Limited evacuations were allowed through Rafah on Nov. 1. Foreign passport holders and injured civilians were let through after days of violence.
The UN said 133,000 people entered and 144,000 exited through the heavily guarded crossing last year. It was open for 245 days.
Egypt allowed humanitarian aid through its Rafah blockade. More than 170 trucks full of aid have passed since mid-October.
Those still in Gaza have set up camp near the border. Hundreds of people have gathered in front of the gates on the Gaza side in recent days.
