A lorry has ploughed into a Christmas market in the heart of Berlin, killing nine people and injuring many more, police say.
Police now say they suspect it was a deliberate attack. Video footage from the scene shows stalls knocked over and people lying injured on the ground.
The driver is believed to be under arrest while the co-driver died.
The market is at Breitscheidplatz, close to the Kurfuerstendamm, the main shopping street in the city's west.
It is situated at the foot of the Kaiser Wilhelm memorial church, which was kept as a bombed-out ruin after World War Two.
As emergency vehicles filled the area, Berlin police appealed to the public to avoid the area and stay at home.
