1973 Westminster bombing

The 1973 Westminster bombing was a car bomb that exploded on Thorney Street, off Horseferry Road, in Millbank, London on 18 December 1973. The explosion injured up to 60 people. The bomb was planted in a stolen car parked in front of the Home Office building when it exploded on Tuesday morning. Two telephone warnings were given within half an hour before the blast. The Provisional Irish Republican Army (IRA) was responsible for the attack, which was assumed to have been in retaliation for the jailing of the Provisional IRA Belfast Brigade members who bombed the Old Bailey earlier in the year. A day earlier, the IRA sent two parcel bombs that targeted two politicians.

It was one of many IRA car bombings in Northern Ireland and England during the Troubles.

Aftermath

The last bombs exploded on Boxing Day 1973 when the Stage Door public house was bombed injuring one person, on the same day another bomb exploded at Sloane Square station there were no injuries in this attack.
