Three police cars set ablaze in Dresden ahead of German Unity Day
BERLIN- Unknown perpetrators set fire to three police cars on Saturday night in the eastern city of Dresden, where security has been tightened for three days of events to mark 26 years since German reunification, police said on Sunday.
Two improvised bombs exploded in the city last week, one at a mosque and one at an international conference centre, and around 2,600 police officers are on duty to safeguard events.
No-one was hurt in Saturday night's blaze, which investigators believe was a politically-motivated act linked to the police operation for the anniversary celebrations.
