As French officials named the alleged ringleader behind the Paris attacks and an international manhunt continues for Salah Abdeslam, more information has emerged about those behind Friday's massacres that left 129 dead.

• Belgian Abdelhamid Abaaoud was named by a French official as the 'presumed' mastermind of the co-ordinated attacks.

An Islamic State (IS) jihadi in his late 20s, he was linked to a thwarted attack on a high-speed train in August which was stopped as it sped towards Paris when passengers overpowered a gunman, and an attack on a church in the Paris area.

Abaaoud grew up in the Brussels suburb of Molenbeek, which has emerged as a key focus of investigations into the Paris atrocity, and is said to have recruited his 13-year-old brother to join him in Syria and become one of IS's youngest fighters.

He is well known to followers of IS and last year a video emerged of him and friends loading a pick-up truck and a trailer with a pile of bloody bodies.

Before driving off in the footage, Abaaoud told the camera: 'Before we towed jet skis, motorcycles, quad bikes, big trailers filled with gifts for vacation in Morocco. Now, thank God, following God's path, we're towing apostates.'

His whereabouts are unknown, but the IS magazine Dabiq suggested he escaped to Syria earlier this year.

• Samy Amimour was one of the suicide bombers who blew himself up at the Bataclan music hall, the Paris prosecutor's office said. A 28-year-old Frenchman, he was known to French intelligence services but apparently slipped through the security net.

He was charged with terror offences in 2012 over an attempted trip to Yemen and links to a network of terror sympathisers and was placed under judicial supervision.

He disappeared the following year and is thought to have joined up with IS in Syria, and an international arrest warrant was issued for him.

Amimour lived at home and had briefly worked as a bus driver, and his father told France's Le Monde newspaper he had travelled to land held by IS last year to try to persuade his son to leave Syria.

Amimour was not interested in what his father said and walked with crutches. The father, who has not been named, said his son was with another man who never left them alone and that he did not tell his father how he was wounded or whether he had been fighting.

After his son's friends showed him horrendous videos of people being murdered, the father left the area for Turkey.

Three members of Amimour's family were arrested on Monday morning, French prosecutors said.

• A suicide bomber who blew himself up outside the Stade de France, the country's national sports stadium, was found with a Syrian passport with the name Ahmad Al Mohammad.

It describes a 25 year old born in Idlib, a rebel-held city in north-west Syria, and the Paris prosecutor's office said fingerprints from the attacker match those of a person who travelled through Greece last month.

Greek officials said someone bearing Al Mohammad's passport was processed on the island of Leros, having arrived there from Turkey. He stayed on the island for five days before travelling to Athens by ship, where authorities stopped tracking him.

It is unclear whether the passport belongs to the attacker.

• Omar Ismael Mostefai, 29, was previously flagged for links to Islamic radicalism, and was named by police after being identified through remains found at the Bataclan music hall.

It was claimed that Turkish authorities identified him as a possible terror suspect in October last year, flagging him up to their French counterparts two months later and again in June this year.

He lived with his family in the French city of Chartres until about two years ago, working as a baker and playing football with colleagues. Residents said he was 'very discreet' and his family was 'very nice', describing him as a 'reserved young man'.

He attended the local mosque with his father until about two years ago, but an Islamic association leader said he showed no signs of being a fanatic.

French police officials believe Mostefai travelled to Syria in the past few years, and that more recently he was placed under increased surveillance.

• Brahim Abdeslam, Salah's elder brother, was named by a judicial source in France as one of the attackers.

The 31 year old was identified by police as the suicide bomber who blew himself up on Boulevard Voltaire. But his mother said he 'did not mean to kill anyone' and believes he may have detonated his suicide vest because of 'stress'.

Another brother, Mohamed Abdeslam, was released without charge on Monday after he was detained at the weekend.

• Another suicide bomber was named as Bilal Hadfi, thought to be 20, one of three who attacked the Stade de France. He is said to have fought with Islamic State in Syria.

• An international manhunt is continuing for Salah Abdeslam, 26, who rented a car used to carry gunmen to the Bataclan music venue in Paris.

The French authorities missed an opportunity to detain their target hours after the carnage in Paris when he was questioned and released on Saturday morning.

Officers had him in their grasp when they stopped the car carrying him and two other men near the Belgian border. On Monday, Belgian police surrounded a suspected hideout in the search for him but came up empty-handed after charging into the property.

The arrest warrant describes Abdeslam, a Frenchman born in Brussels, as very dangerous and warns people not to intervene if they see him.
