French authorities have named one of the attackers as Ismail Omar Mostefai in connection with the string of terror attacks in Paris that left 129 people dead. The 29-year old suspect was a French national.

Mostefai was identified by authorities after his finger was found at one of the attack sites. He was already known to the French police as his fingerprints matched with the authorities' record.

Mostefai's family members including his brother and father are in police custody while his home is being monitored. Mostefai is thought to be from Courcouronnes in Paris's southern suburbs.

The attacker's older brother, who is thought to have voluntarily turned himself in to the police, told the AFP before approaching investigators: "It's crazy, insane. I was in Paris myself last night, I saw what a mess it was."

Ismail's brother said that he has not been in contact with the alleged attacker for several years, who is thought to have been radicalised in 2010, but has not been involved in any terror incident since.

In the series of terror attacks, claimed by Islamic State (Isis), around 129 people have been killed and more than 350 wounded. Some of them are critically injured. Seven attackers, all of them heavily-armed, have been killed.
