Bloody Sunday

An episode on 30 January 1972 occurred in the Bogside region of Derry, Northern Ireland when British officers shot 28 disarmed noncombatants during a demonstration movement against internment. 14 people perished, 13 were murdered unconditional, while the destruction of another people four months later was assigned to his distress. Many of the offerings were killed while escaping from the volunteers and some were killed while attempting to help the injured.
