The suspect, who is reportedly 26-years-old, is one of three brothers wanted by the authorities for allegedly plotting Friday's attacks on Paris.

A senior official privy to the investigation said that authorities suspect that as many as 20 people in Europe plotted the attacks -- from planning, supporting, and carrying out the carnage.

The official said that in January, two brothers, Said and Cherif Kouachi, staged a bloody siege in Paris. He said that the perpetrators of the latest Paris attacks were closely connected with the earlier siege.

Brahim Abdeslam, 31, blew himself up Friday night inside a busy cafe. His 26-year-old brother, Salah, rented a car in Brussels that was used in one of the attacks. He is currently in hiding. A third unnamed brother has been captured by the Belgian police.

Authorities said with all the pieces of evidence coming in, it is apparent that Belgium has become a major base of operations for the jihadists.

At least eight suspects belonging to several death squads are believed to have directly participated in the bloodbath, dubbed France's 9/11.

The eight assailants killed themselves before the French military and the police could swoop down on them. Six detonated their suicide vests while the police shot and killed one suspect..

On Sunday, the French police issued an urgent warning and released a photo of the eighth suspect, Salah Abdeslam. He is said to 5'7 in height and a Belgian-born French national.

As of this writing, the French military has started conducting airstrikes on known ISIS strongholds in Syria as retaliation for the Paris carnage that killed 132 Parisians and wounded scores of others.

French police have staged a manhunt after detaining seven people for questioning. Meanwhile, Belgian authorities have taken seven more suspects into custody. They are believed to have indirectly contributed to the terror attacks in Paris.

ISIS has claimed responsibility for the attacks and announced that it would conduct more massacres in the coming months in countries who make fun of Allah.

French police say that the manhunt has covered the stretch from the Aegean Sea to Paris suburbs and that they hope to capture the remaining terrorists whether alive or not.
