The Rafah border crossing opened Monday for four days, allowing Palestinians to travel in both directions. Crossing director Khaled al-Shaer says some 20,000 people have applied to exit the coastal strip. Gazans seeking medical care and students are among those expected to cross.
Rafah is Gaza's only gateway to the outside world with no Israeli control. Egypt has kept it mostly closed since the militant Hamas group seized control of the area in 2007.
