Key Bloody Sunday questions to be answered

After more than 400 days of evidence and more than 900 witnesses, it is still unclear which soldiers shot 27 civilians on Bloody Sunday, the Saville Inquiry was told today.

Counsel to the inquiry, Christopher Clarke QC, in his closing statement, said the central question before the tribunal was why and how 13 civilians were killed and 14 wounded at a civil rights march in Derry on January 30, 1972.
