Who were the Paris attackers?

(Reuters) - France, which along with Belgium has launched a massive manhunt for people involved in the attacks that killed at least 129 people in Paris on Friday, is striving to establish the identities of the attackers and chief suspects. Following is a list of some of the seven attackers who died, as well as others named in the investigation.

He is believed to have traveled to Turkey at the end of 2013, and investigators suspect he then went to Syria, a judicial source said. An unnamed senior Turkish government official says Turkey contacted France about Mostefai in December 2014 and June 2015 but only got a return request for information on him after the Paris attacks.
