The number of Islamist militant fighters returning to Germany from Syria and Iraq is on the rise and more than 400 people are being watched, the head of German police said on Friday.
Holger Muench, president of the BKA federal police, told ARD television that the number of people leaving Germany for the two countries to fight with militant groups such as Islamic State was dropping.
But there has been a simultaneous rise in the number of fighters returning home.
“The wave of departures is becoming flatter,” he said. “In the meantime, we have more than 400 individuals who pose a threat and whom we must keep an eye on.”
