A Day That Shook The World: IRA bombs British cabinet at Brighton

On 12 October 1984, the IRA attempted to assassinate the entire British cabinet by setting a bomb in the Brighton hotel in which they were all staying ahead of their conference.

Five people were killed in the blast, including one MP, while dozens were injured. Prime Minister Margaret Thatcher herself had a lucky escape, and the next day she gave a defiant speech to the conference, before being whisked away for her safety.
