But they’re not a danger to Europe or U.S…..
Via The Guardian:
The man suspected of shooting dead four people at a Jewish museum in Brussels was an Islamic State militant who tortured his captives, a journalist held by the extremist group has said.
The claim appears to crystallise fears that Europeans who travel to fight with Isis in Syria and Iraq could return to commit atrocities at home.
The French journalist Nicolas Hénin said he was kidnapped in Syria in 2013 and released in April, having been held captive by Mehdi Nemmouche, who was arrested in June for the attack on the museum the previous month.
According to the weekly news magazine Le Point, Hénin said that “when Nemmouche wasn’t singing, he was torturing”.
The journalist, who was released in April, said: “[Nemmouche] was a member of a small group of French nationals whose arrival used to terrify about 50 Syrian prisoners held in cells near ours. Every night, blows would start raining down in the room where I myself had been interrogated. The torture went on all night long, until the dawn prayer.”
