The Llanelli riots of 1911 were a series of events precipitated by the National Railway Strike of 1911. Mass picketing action at Llanelli railway station was brutally suppressed by the police, resulting in the deaths of two men, shot dead by troops of the Worcestershire Regiment. Rioting followed and magistrates' homes were attacked and railway trucks were set on fire, resulting in an explosion which killed a further four people.
