Three explosions have hit a bus carrying the Borussia Dortmund football team to their home Champions League quarter-final match against Monaco.
Player Marc Bartra was injured and was taken to hospital, the club said, but is not believed to be seriously hurt.
The team tweeted (in German) that the other players were safe and there was no danger in or around the stadium.
The first-leg match was postponed and will now be played on Wednesday at 18:45 local time (16:45 GMT).
Pictures from the scene showed the bus’s windows broken in the blasts.
