Egyptian authorities kept the Rafah crossing with Gaza closed for a fourth consecutive day on Saturday.
There have been frequent closures of the terminal in recent weeks as Egypt cracks down on militant groups in Sinai.
The crossing was closed on Aug. 15 after nationwide violence and then partially reopened two days later, only to be closed again following an attack which killed 25 Egyptian soldiers.
Rafah terminal was closed earlier this week after a car bomb outside Egyptian intelligence headquarters in Sinai.
The crossing is the only way most Palestinians in Gaza can enter or leave the territory. Israel imposes an air and sea blockade on the enclave, and its border is closed to Palestinians.
