A number of cars were set on fire by unknown individuals on Tuesday night in the cities of Koeln and Berlin in Germany, said police on Wednesday. In a press conference, spokesperson for Koeln Police said that it was unlikely that the incidents were related to the riots in Paris, noting that there are no riots in Koeln. Spokesperson of Berlin Police also gave similar statements to reporters. Four cars were set on fire in Koeln last night, while six cars and a motorcycle were burned in Berlin on the same night. The security authorities in both cities announced that security measures will be tightened and more police patrols will be on the streets, especially in neighborhoods with residents of lower incomes and higher unemployment rates.
