It Only Takes One, part II

USA Today:

PARIS — A French official identified the suspected mastermind of the attacks that killed 132 people in Paris on Friday as Belgian national Abdelhamid Abaaoud, and said he is believed to be linked to thwarted attacks on a high-speed train bound for the French capital and a church in the Paris area, according to media reports.

French radio station RTL described Abaaoud, 27, as “one of the most active (Islamic State) executioners” in Syria. Reuters reported that Abaaoud is currently in the war-torn country, citing a source close to the investigation.

Two more suicide bombers involved in the attacks were named by authorities Monday. Paris prosecutors named an attacker who blew himself up in the Bataclan music hall Friday as Samy Amimour, a 28-year-old French national who was charged in a terrorism investigation in 2012.

The broadcaster BFMTV reported that three of his relatives were detained by police.

Prosecutors said Amimour was put under judicial supervision but dropped off authorities’ radar in 2013 and an international warrant was issued for his arrest. AFP said Amimour’s family said he went to Syria two years ago.

Another bomber who targeted the national stadium was found with a Syrian passport with the name Ahmad Al Mohammad, a 25-year-old born in Idlib, prosecutors said. Fingerprints from the attacker match those of someone who passed through Greece in October.

The passport’s discovery raised concerns that Islamic State militants may be crossing into Turkey before moving to Western Europe alongside the hundreds of thousands of refugees and migrants who have entered Europe this year, many of them fleeing the civil war in Syria.
