Investigators have identified the sponsor behind the Paris attacks as Abdelhamid Abaaoud, 27, a Belgian native, France RTL radio said.
Abaaoud was reportedly one of the most active Islamic State executioners in Syria. He is believed to be from the Brussels suburb of Molenbeek, the same area where another suspect in the Paris attacks, Salah Abdeslam, was raised.
Abaaoud is a grocer's son from the Belgian town of Molenbeek that has become a by-word for radicalism, financed and organized the attacks. Abaaoud, 27, was believed to be a leader of the cell of returned jihadis involved in deadly shootout with police in the town of Vervier in January. He was sentenced to 20 years jail in absentia, along with 32 other jihadis.
He appeared in Islamic State's English language magazine Dabiq claiming to have rejoined the group in Syria.
Numerous terrorist attacks were conducted in Paris on Nov. 13-14. Four gunmen systematically slaughtered at least 89 young people attending a rock concert at the Bataclan music hall.
Some 40 more people were killed in five other attacks in the Paris region, including an apparent double suicide bombing outside the national stadium where French president Hollande and German foreign minister Frank-Walter Steinmeier were watching a friendly soccer international.
129 people have died in the aftermath of a string of terror attacks in Paris, while 99 out of 352 injured are in a critical condition, Paris Prosecutor Francois Molins stated during a news briefing following a string of terror attacks in France's capital.
