BERLIN (AFP) - A trove of leaked Islamic State in Iraq and Syria (ISIS) group documents features the names of three of the extremist militants behind the deadly attack on the Paris Bataclan theatre, German media reported on Friday.
Among the thousands of ISIS registration papers were those of Samy Amimour, Foued Mohamed-Aggad and Omar Ismail Mostefai, said public broadcasters NDR and WDR and Munich daily Sueddeutsche Zeitung.
The three assailants, using guns and suicide vests, killed 90 people at the Bataclan, the deadliest attack in the bloody rampage that claimed 130 lives across the French capital on Nov 13.
The German research team said it had now obtained data on several thousand ISIS militants from a total of 22,000 documents, many of them doubles, which were earlier also obtained by British broadcaster Sky News.
They contain the names, addresses, phone numbers and family contacts of extremists who joined ISIS, as well as their blood type, mother's maiden name, "level of sharia understanding" and previous experience.
The fighters listed in the cache of documents came from across Europe and from the United States, Russia, Indonesia, South Africa and Trinidad and Tobago, the German media team said.
Germany's federal police said on Thursday it had access to the same type of documents and considered them highly likely to be authentic, but some experts have voiced doubts or urged caution.
The German report said some papers also made indirect reference to Abdelhamid Abaaoud, the organiser of the Paris killings who recruited old friends and other small-time delinquents to help him carry out the attacks.
Omar Mostefai, a 29-year-old French national from a poor Paris suburb, blew himself up at the Bataclan music venue. His identity was confirmed using a severed fingertip found at the scene.
Another Bataclan suicide bomber was 28-year-old Samy Amimour, a former bus driver from the Paris suburb of Drancy, while the third was Foued Mohamed-Aggad, 23, from Strasbourg.
The report said the papers showed that Mohamed-Aggad had arrived in IS territory on Dec 18, 2013, with an unusually large group of French militants that included 14 men and their families.
