The 1972 "Bloody Sunday" shooting, killing 14 protestors, happened in which UK city?

Bloody Sunday, or the Bogside Massacre, was a massacre on 30 January 1972 in the Bogside area of Londonderry, Northern Ireland, when British soldiers shot 26 unarmed civilians during a protest march against internment without trial. Fourteen people died: 13 were killed outright, while the death of another man four months later was attributed to his injuries. Many of the victims were shot while fleeing from the soldiers, and some were shot while trying to help the wounded.

Other protesters were injured by shrapnel, rubber bullets, or batons, and two were run down by army vehicles. All of those shot were Catholics. The march had been organised by the Northern Ireland Civil Rights Association (NICRA). The soldiers were from the 1st Battalion, Parachute Regiment ("1 Para"), the same battalion implicated in the Ballymurphy massacre several months prior.

Two investigations were held by the British government. The Widgery Tribunal, held in the aftermath, largely cleared the soldiers and British authorities of blame. It described the soldiers' shooting as "bordering on the reckless", but accepted their claims that they shot at gunmen and bomb-throwers.
