Defiant in the wake of the Westminster terror attack, Londoners are taking to Twitter to express their solidarity.
Londoners are in mourning after five people were killed and 40 injured in an attack outside the British parliament on Wednesday when a man mowed down pedestrians, then stabbed a police officer before being shot dead.
The car struck pedestrians on Westminster Bridge - a spot popular with tourists because of its views of Big Ben and the Houses of Parliament - before crashing into the railings outside the heavily guarded parliament building.
The police officer and the attacker are among those killed.
Londoners have started a twitter trend #WeAreNotAfraid, in a show of defiance against the attacker - who police suspect was motivated by Islamist terrorism.
