BELFAST (Reuters) -The trial of the sole British soldier charged with murder over the 1972 “Bloody Sunday” killings of 13 unarmed Catholic civil rights marchers in Northern Ireland began on Monday, over half a century on from one of the defining moments of The Troubles.

The soldier, who cannot be identified and is known as Soldier F, is accused of murdering two men and attempting to murder five others when members of a British army regiment opened fire in the mainly Irish nationalist city of Londonderry.

It remains the worst single shooting incident of three decades of sectarian violence involving nationalists seeking a united Ireland, pro-British unionists wanting to remain part of the United Kingdom and British forces. A 1998 peace deal largely ended the bloodshed.
