London is standing strong in the wake of the terror attack in Westminster on Wednesday.
Following the deaths of several pedestrians on Westminster Bridge and a police officer in Parliament's New Palace Yard, staff at several London Underground stations have been erecting signs of hope and courage to encourage passengers to remain defiant.
Daily messages are permanent features at a handful of stations, notably Oval and Clapham North on the Northern line, but it seems more stations have followed suit today.
The signs have quickly gone viral on Twitter as Londoners attempt to make sense of yesterday's attacks, which have left four people dead and dozens injured.
