Ireland, 1972, and the British Embassy in Dublin is under siege from protesters throwing petrol bombs.

Coffins are placed on the doorway to represent the 13 protesters that died in Londonderry in Northern Ireland when British troops fired on an unauthorized civil rights march.

Another protester died later.

This is the immediate aftermath of one of the most traumatic and infamous events in Northern Ireland's history, known as Bloody Sunday.

It drove hundreds of volunteers into the clandestine Irish Republican Army which stepped up its brutal campaign for Northern Ireland to leave the United Kingdom and join the Republic of Ireland.
  
An enquiry at the time largely exonerated the British troops - soldiers from the elite 1st Parachute Regiment.
     
But the families' victims have long sought a new inquiry into the deaths, and in 1998 then UK Prime Minister Tony Blair granted their wish - an inquiry under the British judge Lord Saville was set up. 
   
The 12 year inquiry cost around 200 million pounds and heard evidence from 900 witnesses and statements from many more.

The publication of the Saville report - 38 years after the event - has been met with huge expectation, not least from the families whose loved ones were killed.
