Investigators have identified the voice on an Islamic State audio recording claiming responsibility for the Paris attacks that was posted online.
Citing a person close to the investigation whom it did not name, the news agency said the voice is believed to be that of Fabien Clain, a 35-year-old Frenchman with known ties to radical Islamist networks in the southern city of Toulouse. He was a close associate of Mohamed Merah, the militant who shot and killed seven people, including three Jewish children, in Toulouse in 2012.
Mr. Clain was convicted of recruiting jihadists in 2009 and was sentenced to five years in prison, the news outlets said; after he was released, he went to Syria.
