While police continue their hunt for suspects involved in the attack in Paris that killed at least 129 people, officials have identified five of the attackers along with some of their suspected accomplices.

Seven suicide attackers in total were killed when their explosive vests detonated at three of the targeted sites: the Bataclan concert hall; the Stade de France; and the Comptoir Voltaire café. Other locations in the city were hit, but it is not yet clear which assailants struck where and in what number.

Still at large

1. Abdelhamid Abaaoud: Suspected mastermind

Abaaoud, in his late 20s, is the suspected Belgian mastermind of the attacks. Abaaoud has been linked to earlier plots, including one against a Paris-bound high-speed train that was foiled by three young Americans in August, and the other against a church in the French capital's suburbs.

He was already well known to those who follow ISIS. In 2014, grim footage emerged of him and his friends in Syria loading a pickup and a makeshift trailer with a mound of bloodied corpses.

2. Salah Abdeslam: Suspected of renting black VW Polo car used in attacks

The Brussels-born 26-year-old is the brother of Ibrahim Abdeslam, who blew himself up at the Comptoir Voltair café in Paris. An arrest warrant has been issued for Abdeslam, whom police had allowed to slip from their grasp early Saturday, when they stopped a car carrying three men near the Belgian border.

By then, hours had passed since authorities had identified Abdeslam as the renter of a Volkswagen Polo that carried the attackers to the Paris theatre where so many died. Three French police officials and a top French security official have confirmed that officers let Abdeslam go after checking his ID.

Dead attackers 

Three suicide bombers have been identified as those who targeted the Bataclan concert hall:

1. Ismail Omar Mostefai

The 29-year-old, born just south of Paris and of Algerian descent, was in contact with Abaaoud, the alleged chief planner behind the attacks, one official told the New York Times.

Mostefai had been put on the French intelligence services' "S notice," suspected of being radicalized in 2010. Identified through his fingerprint by officials, Mostefai reportedly entered Turkey in 2013, the Times reported. He is said to have visited Syria in 2013-14 and was flagged by Turkish authorities as a possible extremist in October 2014. A senior Turkish official told The Associated Press that authorities notified French authorities in December 2014 and in June 2015, but had received no response.

At the Anoussra Mosque, Islamic association leader Ben Bammou told AP that Mostefai was a regular mosque-goer until about two years ago. He said Mostefai often attended with his father, but said there was no sign of fanaticism.

2. Samy Amimour

The Frenchman, 28, worked as a bus driver in Paris until 2012, the Guardian reported. He had been under official investigation since October 2012 on suspicion of terrorism-related activity over a plan to go to Yemen and had been the subject of an international arrest warrant since late 2013, when he is believed to have gone to Syria.

At some point, Amimour joined ISIS. His father told the French newspaper Le Monde in 2014 that he had gone to Syria to try to extract his son from ISIS. The father said he had an "extremely cold reunion" with his son and was unsuccessful in bringing him home.

3. The third attacker at the concert hall has yet to be identified

4. Bilal Hadfi

The 20-year-old French national who lived in Belgium also spent time in Syria, according to the Washington Post, citing European intelligence officials. At some point, he returned to Belgium, but disappeared from the radar of the Belgian security services. The Daily Telegraph reported that he fought with ISIS as recently as this spring, under different names.

Although described as a typical teenager with a keen interest in football, Hadfi at some point within the last two years became radicalized by a Belgian imam and began associating with extremists, according to Het Laatste Nieuws.

The Telegraph said Hadfi in July had issued a call on Facebook for attacks on the West.

"To the brothers who reside in the lands of the infidels," he said in a now deleted video post. "Hit the pigs in their communities so they no longer feel safe even in their dreams."

5. Ahmad Al Mohammad

Authorities discovered a passport near the body of one of the attackers that carried the name of Ahmad Al Mohammad, 25, from northwest Syria. Authorities are trying to authenticate the passport, but a Greek official says the fingerprints of the person holding Al Mohammad's passport match up with a person who was processed on the Greek island of Leros after setting out from Turkey.

6. The third suicide bomber has not yet been identified

7. Ibrahim Abdeslam

A 31-year-old French resident of Belgium, Abdeslam was the brother of Salah Abdeslam, one of the key suspects still at large. Abdeslam founded a café that was managed by his brother Salah and was temporarily shut down for drug offences several years ago, the Daily Telegraph reported. The paper said the brothers had recently transferred their shares in the café to another party.

"I used to go there every day after work, on my way home. We would go there to smoke hashish, drink alcohol, no problem," one man, who did not want to be identified, told the Telegraph,

"Ibrahim and I played cards together, we laughed and joked. He talked to everyone, he was very generous ... Ibrahim used to go to discos, he would drink alcohol, smoke. But he stopped drinking alcohol in the last year."
