ITV has apologised after a documentary screened on Monday night presented footage from Arma 2 as a secret IRA propaganda film from 1988.
The broadcaster said the clip in question (below) showed a helicopter being shot down by the IRA using weapons supplied by Colonel Gaddafi. It was in fact fan-made Arma 2 footage.
In a statement, ITV said: "The events featured in Exposure: Gaddafi and the IRA were genuine but it would appear that during the editing process the correct clip of the 1988 incident was not selected and other footage was mistakenly included in the film by producers.
"This was an unfortunate case of human error for which we apologise."
