Paris: Belgium issued an international arrest warrant for one of three brothers linked to the brutal attacks in Paris that killed 129 people, as the probe spread across Europe.
A massive manhunt has been launched to trace 26-year-old Abdeslam Salah. French officials were quoted describing him as dangerous.
Salah's brother Ibrahim died in the Bataclan concert hall where the worst of the bloodshed took place, while his other brother Mohamed was detained along with six other people in Molenbeek area of Belgium.
Authorities in at least five European countries scrambled to tie together leads and hunt down possible accomplices even as thousands gathered in central Paris to mourn the victims of the senseless act of terror.
Initially, it was suggested that eight men were involved in the attacks. However, seven gunmen wearing suicide belts died during the attacks, which have been claimed by the Islamic State group.
Salah may the eight suspect.
The sports minister said at least one of the bombers who detonated their explosives near the stadium had tried to enter the venue where France were playing Germany in an international football match at the time.
Prosecutors say they believe three groups of attackers were involved in the Paris carnage, raising the possibility that one group may still be at large.
Two cars used in the attacks were hired in Belgium. One was quickly found near the Bataclan venue, and one overnight yesterday in the suburb of Montreuil east of Paris, with two AK47 rifles inside.
The first attacker to be named by investigators is Omar Ismail Mostefai, a 29-year-old father and French citizen, who was identified from a severed finger among the carnage at the Bataclan, where 89 people were killed after heavily armed men in wearing explosives vests stormed into the venue.
France bombs Islamic State 'capital' Raqqa
French warplanes pounded the Islamic State (IS) group's de facto Syrian capital Raqa, destroying a command post and a training camp, the defence ministry said.
In its first air strike yesterday against IS since the string of deadly Paris attacks claimed by the jihadist group, 12 warplanes, including 10 fighter bombers, dropped 20 bombs on the targets.
The planes left from Jordan and the United Arab Emirates and was conducted in coordination with American forces, the ministry said.
