The only British soldier charged over Bloody Sunday entered the dock for the start of his controversial murder trial on Monday.

The former paratrooper, now in his 70s and known only as Soldier F, is accused of killing two of the 13 civil rights demonstrators who lost their lives on January 30, 1972.

The fateful day in Londonderry, when soldiers from the Parachute Regiment shot 26 unarmed civilians during a protest march, was an early flashpoint in the Troubles.

The alleged actions of Soldier F were described on Monday as an 'unjustified' and 'gratuitous' use of force that 'disgraced the Army'.

Shielded in the glass-pannelled dock by a black plastic cover to protect his identity, Soldier F listened as the case was outlined against him in Belfast Crown Court.
