The hashtag #bedforawayfans went viral in the wake of the shock attack on Borussia Dortmund's team bus just minutes before their Champions League game with Monaco.

Three explosions occurred as the Dortmund squad were travelling to the Signal Iduna Park stadium for Tuesday's quarter-final first leg and the game was subsequently postponed and rescheduled to be played on Wednesday.

That left thousands of Monaco supporters left facing an extra night in Germany but in a touching gesture were offered emergency accommodation by Dortmund fans via the hashtag #bedforawayfans on social media.
