A 23-year-old man from the eastern French city of Strasbourg has been identified as the third bomber involved in the Nov. 13 attacks at Paris's Bataclan music hall, police sources said Wednesday. Foued Mohamed Aggad went to Syria with his brother and a group of friends at the end of 2013, according to a source close to the investigation. Most of the others were arrested in spring last year upon their return to France but Aggad stayed on in Syria, the source said. The Bataclan shootings were part of a co-ordinated attack that killed 130 people in Paris and which was claimed by the Islamic State group. Ninety people died in the Bataclan attacks on November 13. The two other bombers have been named as Samy Amimour, 28, from Drancy, northeast of Paris, and Ismail Omar Mostefai, 29, who lived in Chartres, southwest of Paris. Aggad was identified at the end of last week after his DNA was matched with those of his family members, the police source said.
