From 1960s into the 1990s, the Provisional Irish Republican Army carried out a wave of deadly attacks across the U.K. aimed at ending British rule in Northern Ireland - including bombings of historic landmarks.
There were an estimated 500 incidents during "The Troubles," mainly in London, with 50 people dying in the capital, including 28 civilians, 15 soldiers and five police officers, and two IRA members, Wikipedia said.
One of the most heinous occurred July 20, 1982, when the IRA bombed the Queen’s Life Guard. "Fifteen mounted soldiers of the Household Cavalry were in Hyde Park on their way to change the guard near Buckingham Palace when a remote-controlled car bomb was detonated, blasting them with nails and other shrapnel," according to the UK Army Museum. Four soldiers and seven horses died.
On March 8, 1973, the IRA hit the Old Bailey, London's central criminal court. Twin car bombs claimed one life. Another 100 people were injured. The blasts also damaged government agricultural offices.
On June 17, 1974, a bomb at the Houses of Parliament fractured a gas main. "A fierce fire spread quickly through the centuries-old hall in one of Britain's most closely-guarded buildings,'' the BBC said. About a dozen people were injured.
A month later, July 17, 1974, a blast at the Tower of London killed one person and injured about 40 others. The bomb detonated in the Mortar Room in the White Tower, a small basement exhibition room packed with tourists.
On Dec. 17, 1983, bombers struck London's Harrods Department Store during the Christmas shopping season. The explosion killed six people, including three police officers, and wounded scores more.
On April 24, 1993, a truck bomb at Bishopsgate in the City of London caused £1 billion in property loss, including the destruction of a church and serious damage to the Liverpool Street Underground. One person died and 44 were injured.
