1 soldier killed, 3 injured in armed attacks in Egypt\'s Sinai

At least one soldier was killed and three others injured in an armed attack by Islamist extremist groups in North Sinai, a security source in Sinai told Xinhua. An exchange of fire between the extremists and the security forces is still going on, said the source. The source added that hundreds of gunmen attacked Arish Airport, a security camp in Rafah, a police station and two security checkpoints in Sheikh Zewaid by heavy artillery and rocket-propelled grenades in North Sinai that led to the killing of a soldier and injured three others. The attacks came after the Egyptian army ousted Islamist-oriented president Mohamed Morsi on Wednesday in response to millions of protesters who took to the streets and public squares across the country demanding his removal. Islamist supporters of the ousted president rejected his ouster as \"a military coup\" and vowed to struggle for Morsi\'s legitimacy. Armed attacks on police and military premises and checkpoints prevailed in Sinai Peninsula due to lack of security following the 2011 mass protests that ousted ex-president Hosni Mubarak.
