GAZA CITY (Ma'an) -- Israeli authorities will keep the Kerem Shalom crossing with Gaza closed on Sunday, a Palestinian border official said.

Nathmi Muhanna, PA director of border crossings, told Ma'an Saturday that the crossing will be closed for "security reasons."

Kerem Shalom has remained shut since Monday, when a projectile fired from Gaza struck Israeli territory, but was scheduled to be reopened Sunday.

On Friday, an Israeli military spokeswoman said Palestinians hurled rocks and firebombs over the fence at army patrols in several locations and that militant gunfire damaged an army vehicle.
