Several people have been rescued from Berlin's Zoo train station after smoke enveloped one of its platforms. The station in the Charlottenburg district had to be completely evacuated.
Railway traffic was stopped at Berlin's Zoologischer Garten train station in the early afternoon due to a large amount of smoke. Some 21 people were rescued from the area with the most smoke, German police said on Twitter on Sunday afternoon.
A fire department spokesman told the German press agency DPA that the fire broke out in a fenced-off construction area.
German media showed smoke coming out of the station, near the site of the December 2016 Christmas market attack.
The fire service tweeted: "Ventilation continues. So far 1 injured person."
The city fire service tweeted: "Heavy smoke, several people rescued from #driving area."
Local S-Bahn services had to be rerouted, with one train with about 250 people on board being returned to Tiergarten station.
Long distance and regional rail services, which run through the station, resumed a few hours later, although they couldn't stop there.
Germany is on high alert for potential terror attacks a year after a failed Tunisian asylum seeker ploughed a truck into a Berlin Christmas market, killing 12 people.
