The public service broadcaster committed a "significant breach" of media regulations by omitting to mention that the voice of a film about Gaza was the son of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to accuracy".
The authority has ordered the broadcaster to transmit a evening announcement about its findings.
"Given this constitutes a major infringement of our rules, we are directing the broadcaster to air a announcement of our findings against it on BBC2 at 9pm, with a date to be confirmed," it said.
'Possibility to Damage Credibility'
The authority's announcement stated: "Our investigation found that the programme's omission to reveal that the voice's parent occupied a position in the Hamas-run administration was substantially inaccurate.
"Consequently that the public did not have vital facts which may have been highly relevant to their evaluation of the presenter and the information he provided.
"Confidence is at the heart of the relationship between a media organization and its audience, particularly for a state-funded media outlet such as the public broadcaster.
"This error had the possibility to erode the very considerable amounts of credibility that audiences would have invested in a BBC factual programme about the Gaza conflict."
The film was pulled from iPlayer in the month of February after the presenter's personal associations were revealed, and in the month of July an corporation's own inquiry concluded it infringed the organization's journalistic standards on accuracy.
A corporation official commented: "The regulator's decision is in accordance with the results of the corporation's inquiry, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which reflects regulation 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the authority's determination in its entirety. We will adhere to the sanction as soon as the timing and wording are determined."
