CAIRO Four people were wounded on Wednesday when rocket-propelled grenades were fired at a military facility in Egypt's Sinai Peninsula, state television reported.
Witnesses said they heard loud explosions in the area. The Sinai, which borders Israel and the Gaza Strip, has seen a sharp rise in militant attacks since the army ousted Islamist president Mohamed Mursi in July.
In a separate incident, an explosion hit an army checkpoint in the al Imam Ali district of Rafah in northern Sinai, close to the Gaza border. Witnesses said clashes between militants and military forces were taking place in the area.
