German arrests 'could be linked to Paris'

German police say they are investigating whether two men arrested a day earlier over suspicions they were preparing attacks in Berlin are linked to the attacks in Paris last year.

"We are investigating whether there is a link to the Paris attacks," police spokesman Stefan Redlich said on Friday.

Police and special forces on Thursday raided four flats and two offices in Berlin and properties in the northern regions of North Rhine-Westphalia and Lower Saxony, arresting two Algerian men.

Police on Friday published a photo of one of the two men arrested with a gun in his hand and surrounded by weapons at an unnamed location.
