CAIRO, Aug. 15 (Xinhua) -- Unidentified militants on Tuesday shot a policeman dead in Egypt's North Sinai province, an official security source said.
"The gunmen opened fire on him while heading for the morning prayers," the source told Xinhua.
The security men started a massive manhunt operation in search for the perpetrators, he added.
Egypt is experiencing wave of terrorist attacks which target the security men since the ouster of the Islamist president Mohamed Morsi in 2013 in response to mass protest against his one-year in rule.
The attacks that have killed hundreds of military and police men were mostly claimed by Islamic State branch in Sinai.
