A witness who was 14 years old on Bloody Sunday told yesterday how he saw a body on the ground as firing continued, but only found out later that it was that of his 17-year-old brother, Jackie Duddy.
Mr Gerry Duddy said that when he returned home to the Creggan, his sister told him that Jackie had been shot - "I couldn't believe it. I wanted to get a gun and shoot the bastards who had done it," he said in his statement to the inquiry.
Jackie Duddy, the first person shot dead on Bloody Sunday, had parted company with his brother only minutes earlier, after a brief conversation in Rossville Street.
Both teenagers had been told by their parents that morning they were not to go on the Civil Rights march. Mr Gerry Duddy said yesterday, however: "I could see thousands of people walking past outside our front door. "As far as I was concerned I was going to go on the march. I had to avoid my Da as I sneaked out of the house."
A woman who later became a Sinn Fein official and councillor in Derry described how she "ran for her life" in Rossville Street as the paratroopers invaded the Bogside.
Ms Anne Harkin, known later under her married name as Mrs "Dodie" McGuinness, and as a member of the Sinn Fein ardchomhairle, told the inquiry she was 22 years old when she went on the march. When she heard the roar of armoured vehicle engines, and then shots, she ran south on Rossville Street with hundreds of other people who were fleeing in panic.
She had to clamber over the rubble barricade outside Rossville Flats, "and as I did so I grabbed someone's hand and pulled them over the barricade", she said. "To this day, I do not know who this was. Once on the south side of the rubble barricade, still holding on to the stranger's hand, I ran for my life . . ."
Earlier the inquiry heard evidence given in Irish by another witness, a former teacher, Mr Padraig O Mianain. Simultaneous translation of Mr O Mianain's evidence and cross-examination was provided by an interpreter.
Mr O Mianain described assisting a young man, later named as Damien Donaghy, who was shot and wounded in the William Street area a short time before the paratroopers entered the Bogside.
O Mianain's preliminary sworn statement to the inquiry taken in Irish, because he had expressed a preference to that effect. This was done "as a matter of courtesy", according to inquiry sources.
The inquiry continued hearing civilian witnesses yesterday and there was no judicial reference to the legal impasse reached last week over British government efforts to have certain Security Service material withheld from publication.
It is understood a written ruling on the matter will be issued by the tribunal in due course.
The hearings continue today.
