French authorities have identified the third attacker who blew himself up at the Bataclan concert hall in Paris last month in the deadliest attacks on French soil since World War II, French media reported Wednesday.

France’s Agence France-Presse identified the 23-year-old man as Foued Mohamed-Aggad, from the French city of Strasbourg. Citing a source close to the investigation into the deadly attacks, the agency reported that the man went to Syria with his brother and a group of friends at the end of 2013.

French Prime Minister Manuel Valls confirmed on the French television station, BFMTV, that the third attacker at the Bataclan has been identified. The bodies were difficult to identify because the men detonated suicide vests after gunning down members of the audience in the Nov. 13 terrorist assault.

Mohamed-Aggad was identified at the end of last week by DNA matching after his mother received a text message confirming his death, news agencies reported, quoting French authorities.

Most of the other men who traveled to Syria with Mohamed-Aggad were arrested in spring last year upon their return to France, but Mohamed-Aggad stayed in Syria, AFP and the French newspaper Le Parisien reported.

Ninety people died at the concert hall after three gunmen stormed a rock concert by the California band, Eagles of Death Metal. In all, 130 people died in the multi-pronged attacks in Paris. Other targets were a soccer stadium north of the capital and several restaurants and cafes.

The two other bombers have been identified as Ismael Omar Mostefai, 29, from Chartres, southwest of Paris, and Samy Amimour, 28, from Drancy, northeast of Paris.

Amimour also spent time in Syria, as did the presumed ringleader of the Nov. 13 attacks, Abdelhamid Abaaoud, 28, a Belgian of Moroccan origin. Abaaoud was killed the week after the attacks in a dawn police raid near Paris.

Another attacker, Salah Abdeslam, 26, French but born in Brussels, is still at large, despite a massive international dragnet to apprehend him.

The attacks were claimed by the Islamic State, a radical al-Qaeda offshoot also known as ISIS that now controls large parts of Syria and Iraq.

Mohamed-Aggad’s older brother, Karim, who also visited Syria, is in jail in France, the Reuters news agency reported, citing a judicial source.

The identification came after Mohamed-Aggad’s mother received a text message announcing his death and gave a DNA sample to police, according to the Associated Press.

The mother received a text message in English about 10 days ago announcing her son’s death “as a martyr” on Nov. 13 — a typical way that the Islamic State notifies families of casualties, AP said. She then gave French police a DNA sample, which led to the conclusion that Mohamed-Aggad died inside the Bataclan, according to his brother’s lawyer, Françoise Cotta.

The latest information means that all attackers identified so far were French or Belgian, and all were native French speakers.
