A television news cameraman said that he and his crew were
interrupted three times by bursts of firing as they tried to interview Fr Edward (now Bishop) Daly on Bloody Sunday, and he believed the shots came from the direction of the city walls.
Mr Cyril Cave, a veteran BBC cameraman, now retired, who covered the Northern Troubles from their inception, also said that he and a BBC reporter received a warning from army officers they met in advance of the Civil Rights march on January 30th, 1972, when 13 civilians were shot dead.
Mr Cave said that one of the officers was a Major in the resident battalion in Derry, and the other was a Parachute Regiment Captain who is now General Sir Michael Jackson, one of the most senior officers in the British army.
One of the officers asked him and his reporter what they were doing that day, he said, and he replied that they were with the marchers. "The two soldiers looked at each other and then one of them said 'You watch yourself'," Mr Cave continued.
"I then said something like 'Why, is there going to be lead flying around or something?' One of them then replied 'Just be careful'."
Mr Cave went on to describe the movements of himself and his camera crew before and during the intense shooting, as he captured some of the most vivid images of the bloodshed and chaos.
He identified a shout from the crowd on the soundtrack of a section of his film taken as casualties were being carried to an ambulance. The voice shouts: "Take care - they're shooting from the walls."
He also identified as the "zip", or whine of a passing bullet, a sound recorded on the film as soldiers run across waste ground. He believed that this could have been 'incoming fire', as he assumed the soldiers would not have been firing at their own men.
The witness said that afterwards, as they tried to leave the area, soldiers refused to let them through the main army barrier on William Street. They spotted General Robert Ford on the other side, and he agreed to be interviewed.
"The soldiers then let us through the barrier to talk to Ford," said Mr Cave. "We did the interview and then headed back to the hotel where the film was despatched to Belfast in a taxi.
"It was my feeling at the time that had Ford not let us through to interview him, the soldiers manning the barrier would have kept us there to prevent our footage going out on the news. As it was, we provided 13 minutes of footage on the evening's bulletins."
The inquiry resumes on Monday.
