Maher Abu Sabha, the Palestinian official in charge of border crossings, said the Palestinian Authority was notified Rafah would be closed until further notice, the Ma'an news agency reported. Rafah is Gaza's only exit for most of its residents because the border with Israel is generally closed.
Militants fired rockets and machine guns at a checkpoint near the village of al-Gura in the northern Sinai and at a police station, witnesses said. Two soldiers were wounded in the attacks and one was killed.
The militants accuse the Egyptian military of a coup against former President Mohamed Morsi, who was ousted this week.
