The BBC engaged in a "major breach" of media regulations by omitting to mention that the presenter of a programme about the Gaza situation was the child of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The head of the BBC had earlier expressed regret, stating there had been "a major oversight in relation to truthfulness".
The authority has ordered the broadcaster to transmit a peak-time statement about its findings.
"Given this constitutes a major infringement of our rules, we are ordering the corporation to broadcast a statement of our conclusions against it on BBC2 at nine o'clock in the evening, with a schedule to be confirmed," the regulator stated.
'Potential to Undermine Credibility'
The watchdog's statement declared: "Our probe determined that the film's lack of disclosure that the voice's father occupied a position in the Hamas-run administration was significantly deceptive.
"This implied that the audience did not have vital facts which may have been extremely pertinent to their judgment of the presenter and the information he shared.
"Trust is at the heart of the bond between a television network and its viewers, especially for a state-funded media outlet such as the public broadcaster.
"This failing had the potential to undermine the very considerable amounts of trust that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The documentary was removed from the online platform in last February after the narrator's familial connections came to light, and in July an corporation's own inquiry determined it infringed the organization's content policies on accuracy.
A representative for the broadcaster commented: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will follow the directive as soon as the schedule and wording are finalised."
