BERLIN (Reuters) - Railway workers foiled an arson attack on Berlin's central station Monday after discovering incendiary devices left at the mouth of an entrance tunnel.
Hours earlier another suspected arson attack had damaged signals and cables on the major Hamburg to Berlin line, police said.
A German leftwing group claimed responsibility for the attacks, saying it wanted to protest the presence of German troops in Afghanistan and exports by the German defense industry.
Police said the incendiary devices appeared to be the same at both sites. According to Deutsche Bahn train traffic was disrupted for one and half hours, while police and staff made the railway track safe.
Last November arsonists attacked Berlin's subway train network, causing huge disruption. Several hundred cars have also been set alight by arsonists in the capital this year.
Germany has around 5,200 soldiers deployed as part of NATO's mission in Afghanistan, most of them in the north.
