The public service broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the presenter of a film about Gaza was the offspring of a Hamas representative, as determined by British broadcasting authority Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, saying there had been "a major oversight in relation to truthfulness".
The authority has directed the broadcaster to transmit a peak-time announcement about its findings.
"Since this amounts to a major infringement of our rules, we are instructing the broadcaster to air a announcement of our determinations against it on BBC Two at nine o'clock in the evening, with a date to be confirmed," the regulator stated.
'Potential to Erode Trust'
The authority's statement stated: "Our probe concluded that the programme's omission to reveal that the presenter's father served in a role in the Hamas-administered administration was significantly deceptive.
"This implied that the audience did not have critical information which may have been highly relevant to their assessment of the presenter and the information he shared.
"Confidence is at the center of the connection between a media organization and its viewers, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to undermine the significantly high amounts of confidence that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was withdrawn from iPlayer in February after the presenter's family links were revealed, and in July an internal BBC review found it breached the corporation's journalistic standards on accuracy.
A representative for the broadcaster commented: "The authority's determination is in agreement with the conclusions of the internal assessment, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which reflects clause 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with the regulator's ruling in complete. We will follow the directive as soon as the timing and wording are finalised."
