A group linked to Al-Qaida's North Africa branch in Tunisia says it has executed a shepherd it abducted Sunday from a mountainous zone near the Algerian border.

The Oqba Ibnou Nafaa brigade claimed responsibility for the killing in a message on its Twitter account. It accused the shepherd of informing police about the group's movements.

The group also claimed responsibility for the killing of two Tunisian soldiers and wounding three others who had conducted a sweep of the area following the shepherd's abduction.
