The Saville Inquiry into the events which occurred on Bloody Sunday resumed today in Co Derry where written submissions are to be examined over the next two weeks.
Two further witnesses are to take the stand in the city's Guildhall to give their accounts of the events in January 1972 when 13 civil rights marchers were shot and killed by paratroopers.
Brendan Duddy, a prominent businessman, and Daniel McGilloway, the father-in-law of an alleged IRA member at the time, bring to 921 the total number of witnesses who will have appeared before the Inquiry.
The investigation has so far cost £155m, and its report is expected to be published by the summer of next year.
