Belgian authorities have revealed the last suspect in the probe into the terror attack on Paris in November 2015. A Syrian man, Omar Darif, was named by the investigation. 

Investigators building a case against Salah Abdeslam for the bomb and gun attack on the French capital on November 13 2015 have named the final man suspected of involvement. 

According to Belgian newspaper Het Laatste Nieuws a key witness recognized the photograph of Omar Darif when shown by prosecutors. 

Darif, who is Syrian, was known by several pseudonyms but never confidently identified. He is understood to have arrived in France in the days before the November 13 attack, and reportedly bought materials and assembled explosives. His DNA was found on belts and materials worn by Salah and Brahim Abdeslam in the attack. 

It is understood that a Syrian refugee was key to the revelation. Now working in a bakery in Flanders, he fled the civil war in his home country. He was able to identify Darif because his family members had connections to ISIL. There is no suggestion the witness had any terrorist connection. 

The same witness helped prosecutors identify another Syrian man - Obeida Aref Dibo - who was named by officials in November, and is suspected of training the terrorists.
