The public service broadcaster committed a "significant breach" of industry standards by omitting to mention that the voice of a documentary about the Gaza conflict was the child of a Hamas representative, according to regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has ordered the BBC to broadcast a evening declaration about its decisions.
"Since this amounts to a significant violation of our rules, we are directing the BBC to broadcast a statement of our findings against it on BBC Two at nine o'clock in the evening, with a date to be determined," the regulator stated.
'Potential to Undermine Trust'
The regulator's announcement declared: "The inquiry we conducted determined that the documentary's omission to reveal that the voice's parent occupied a position in the Hamas-controlled administration was substantially inaccurate.
"It meant that the audience did not have vital facts which may have been highly relevant to their evaluation of the narrator and the details he provided.
"Confidence is at the core of the relationship between a media organization and its public, especially for a public service broadcaster such as the public broadcaster.
"This error had the risk to damage the very considerable amounts of credibility that audiences would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was removed from the BBC's streaming service in the month of February after the presenter's familial connections emerged, and in the month of July an broadcaster's internal assessment determined it infringed the corporation's editorial guidelines on accuracy.
A corporation official stated: "The Ofcom ruling is in accordance with the results of the internal assessment, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept the authority's determination in full. We will follow the directive as soon as the schedule and wording are finalised."
