EL-ARISH, Egypt (Ma'an) -- A man from the Gaza Strip was stabbed to death on Thursday in el-Arish, a city in Egypt's Sinai, security sources said.
The body of Jamal Madi Ibrahim was found near Ayoub Mosque in el-Arish with multiple stab wounds, Egyptian security officials told Ma'an.
Ibrahim left Gaza in 2007, when Hamas took over the enclave after winning a brief civil war against Fatah.
Also Thursday, a Bedouin man was killed in armed clashes between two tribes in a village near Bir el-Abd, west of el-Arish. Clashes in the village are ongoing and several people have been injured, a Ma'an reporter said, adding that the situation could escalate.
Egypt's security crackdown on Sinai continued Thursday as military helicopters were dispatched to monitor "terrorist strongholds" in the peninsula, security officials said.
Forces are trying to restore security to the area which officials say has been infiltrated by Jihadist groups since the overthrow of President Hosni Mubarak in February 2011.
Egypt's Islamist president, Mohamed Mursi, has pledged to restore security in the area.
Egyptian authorities have been searching for armed militants since the ambush and killing of 16 border guards on Aug. 5. The government sent troops backed up by tanks, armored vehicles and helicopters to raid militant hideouts, arrest suspects and seize weapons in the biggest security operation in Sinai.
Efforts to impose central authority in the lawless desert region are complicated by the indigenous Bedouin population's ingrained hostility to the government in Cairo.Reuters contributed to this report.
