LONDON (AP) - Prosecutors have charged an Irish man with four murders stemming from a bomb attack in Hyde Park on July 20, 1982.

The attack killed four members of the Royal Household Cavalry as they travelled from their barracks to Buckingham Palace during a time of political violence related to the conflict in Northern Ireland.

Prosecutors said on Wednesday that Anthony Downey, 61, has been charged with being responsible for the improvised explosive device in a car parked along their route.

Downey is set to appear in Westminster Magistrates Court later on Wednesday. He is charged with murder and with intending to cause an explosion likely to endanger life.
