Two suspects still wanted after Abdeslam arrest

The arrest in Brussels of top Paris attacks fugitive Salah Abdeslam leaves two suspects still on the run since the jihadist rampage in November that claimed 130 lives.

Following is a summary of what investigators know so far about the pair on their wanted list.

- Mohamed Abrini -

Abrini and Abdeslam became friends when they were teenagers, according to their families, who are next-door neighbours in the Brussels district of Molenbeek, a known hotbed of Islamist radicalism.

Nicknamed "Brioche", the 31-year-old Belgian of Moroccan origin is thought to have given up training as a welder at age 18 and begun gravitating towards the extremist milieu.

Previously known to Belgian police for a series of thefts and drug-related offences, Abrini is suspected of helping to plan the Paris attacks.

His arrest warrant issued by a French judge on November 24 warns he is "dangerous and probably armed".

He is of "athletic build, 1.8 metres (five feet 11 inches) tall, dark hair, dark eyes (and) fine features", it reads.

There has been no trace of Abrini since November 12, the day before the Paris attacks.

He is known to have travelled abroad several times last year. In June, he flew to Istanbul, from where investigators believe he may have travelled to Syria for a brief period.

His younger brother Souleymane was killed in 2014 at age 20 while fighting in an Islamist militia headed by Abdelhamid Abaaoud, the ringleader of the Paris attacks who was killed in a police raid on November 18.

Abrini was spotted in mid-July in Birmingham, the British hub of Islamist extremism.

The next month he was in Germany and Morocco, but he disappeared from the radar until November 10.

Abrini travelled by car with Salah Abdeslam and his brother Brahim on November 10 and 11 when the trio made two round-trips between Brussels and Paris to rent hideouts for the attackers.

Brahim Abdeslam blew himself up at a restaurant during the November 13 attacks in Paris targeting a concert hall, bars and restaurants and the national Stade de France stadium.

On November 12, Abrini was spotted at a Belgian petrol station near the French border in one of the cars taking the attackers to Paris.

He has not been seen since, although relatives say Abrini, who has three brothers and two sisters, was in Brussels on the evening of November 13.

Investigators are unsure whether he took part in the Paris attacks, helped with logistics or acted only as a driver.

- Soufiane Kayal -

The real name of the second fugitive is unknown. He used false papers in the name of Soufiane Kayal at the border between Austria and Hungary on September 9 when he was travelling with Abdeslam and Mohamed Belkaid, a 35-year-old Algerian who was shot dead on Tuesday during a police raid in Forest, southwest of Brussels.

The three men posed as tourists heading to Vienna on holiday and did not raise suspicions.

One hideout in central Belgium, a house near the town of Namur, was rented in the name of Soufiane Kayal.

Investigators suspect that Kayal and Belkaid were in telephone contact with some of the attackers on the evening of November 13. They say there is a "strong possibility" that Belkaid was the recipient in Brussels of a text message saying "It's started", sent at 9:42 pm from the Bataclan concert hall as the massacre of 90 people began.

A second Belgian phone in the same location called Abaaoud that evening.

On November 17 Belkaid used a fake ID in the name of Samir Bouzid to transfer 750 euros ($845) to Hasna Ait Boulahcen, Abaaoud's cousin, so she could find him a hiding place in the Paris area.

A search warrant was issued on December 4 for the Kayal and Bouzid aliases.

Belgian investigators say Bouzid is "more than likely" the alias used by Belkaid.
