500 “̶G̶e̶r̶m̶a̶n̶ ̶c̶i̶t̶i̶z̶e̶n̶s̶”̶ Muslims who fought with ISIS under surveillance in Euro 2016

Some 500 Germans who have fought with terrorist group “Islamic State” are under surveillance during the Euro 2016 soccer championship. Germany kicks off its Group C campaign against Ukraine in Lille on Sunday.

German Interior Minister Thomas de Maiziere told the “Bild am Sonntag” newspaper that security forces have received many tip-offs regarding possible attacks at Euro 2016, but added that there had been no concrete indications a terrorist attack was imminent during the tournament.

“There are officially some 500 threats that we have in our sights,” he told the mass-market paper. “That is very extensive, but subject to change.”

Germany has been on high alert for several months since the attacks last year in Paris and this year in Brussels. It’s not known exactly how many German citizens are fighting or have fought in Syria or Iraq with IS, but estimates put the number in the hundreds.
