German police conducted raids and arrested two suspects on Thursday in an investigation of four Algerian men who are suspected of planning an attack in Germany and having ties to Islamic State.
The arrests were made in Berlin and at a refugee home in the western town of Attendorn, Berlin police spokesman Stefan Redlich said.
Authorities suspect that the four men had contacts with ISIS and say that one of them - the man arrested in Attendorn - is sought by Algerian authorities for belonging to the extremist group.
His wife is also wanted by Algerian authorities and was arrested, though she isn't a suspect in the German case, Berlin prosecutors' spokesperson Martin Steltner said.
