Algiers - The Islamic State group has claimed responsibility for the killing of an Algerian police officer while he was reportedly dining in a restaurant.
The group has been trying to expand in Algeria, where al-Qaeda's North African branch and other Islamic extremist groups have been based and have long fought Algerian authorities.
The ISIS-affiliated Amaq news agency said in a statement that ISIS fighters shot the officer and seized his weapon in the attack Friday in Constantine, 400km east of the capital Algiers. It later posted a picture of what it said was the officer's gun.
Algerian authorities confirmed the police officer was killed by an unnamed "terrorist group", but didn't provide details or comment on the ISIS claim. The attackers are at large.
