Bloody Sunday (Irish: Domhnach na Fola) - sometimes called the Bogside Massacre - was an incident on 30 January 1972 in the Bogside area of Derry, Northern Ireland, in which 26 unarmed civil-rights protesters and bystanders were shot by soldiers of the British Army. Thirteen males, seven of whom were teenagers, died immediately or soon after, while the death of another man four-and-a-half months later was attributed to the injuries he received on that day. Two protesters were also injured when they were run down by army vehicles. Five of those wounded were shot in the back. The incident occurred during a Northern Ireland Civil Rights Association march; the soldiers involved were members of the First Battalion of the Parachute Regiment (1 Para).

Two investigations have been held by the British government. The Widgery Tribunal, held in the immediate aftermath of the event, largely cleared the soldiers and British authorities of blame—Widgery described the soldiers' shooting as "bordering on the reckless"—but was criticised as a "whitewash", including by Jonathan Powell. The Saville Inquiry, chaired by Lord Saville of Newdigate, was established in 1998 to reinvestigate the events. Following a 12-year inquiry, Saville's report was made public on 15 June 2010, and contained findings of fault that could re-open the controversy, and potentially lead to criminal investigations for some soldiers involved in the killings.The report found that all of those shot were unarmed, and that the killings were both "unjustified and unjustifiable." On the publication of the Saville report the British prime minister, David Cameron, made a formal apology on behalf of the United Kingdom.

The Provisional Irish Republican Army's (IRA) campaign against the partition of Ireland had begun in the two years prior to Bloody Sunday, but public perceptions of the day boosted the status of, and recruitment into, the organisation enormously. Bloody Sunday remains among the most significant events in the Troubles of Northern Ireland, chiefly because it was carried out by the army and not paramilitaries, in full view of the public and the press.

Sunday, Bloody Sunday - U2

Yes...

I can't believe the news today
Oh, I can't close my eyes
And make it go away
How long...
How long must we sing this song
How long, how long...
'cause tonight...we can be as one
Tonight...

Broken bottles under children's feet
Bodies strewn across the dead end street
But I won't heed the battle call
It puts my back up
Puts my back up against the wall

Sunday, Bloody Sunday
Sunday, Bloody Sunday
Sunday, Bloody Sunday

And the battle's just begun
There's many lost, but tell me who has won
The trench is dug within our hearts
And mothers, children, brothers, sisters
Torn apart

Sunday, Bloody Sunday
Sunday, Bloody Sunday

How long...
How long must we sing this song
How long, how long...
'cause tonight...we can be as one
Tonight...tonight...

Sunday, Bloody Sunday
Sunday, Bloody Sunday

Wipe the tears from your eyes
Wipe your tears away
Oh, wipe your tears away
Oh, wipe your tears away
(Sunday, Bloody Sunday)
Oh, wipe your blood shot eyes
(Sunday, Bloody Sunday)

Sunday, Bloody Sunday (Sunday, Bloody Sunday)
Sunday, Bloody Sunday (Sunday, Bloody Sunday)

And it's true we are immune
When fact is fiction and TV reality
And today the millions cry
We eat and drink while tomorrow they die

(Sunday, Bloody Sunday)

The real battle just begun
To claim the victory Jesus won
On...

Sunday Bloody Sunday
Sunday Bloody Sunday...
