The public service broadcaster engaged in a "major breach" of media regulations by omitting to mention that the presenter of a programme about Gaza was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a significant failing in relation to accuracy".
The regulator has ordered the BBC to air a peak-time statement about its findings.
"Since this amounts to a serious breach of our regulations, we are ordering the broadcaster to transmit a announcement of our findings against it on BBC2 at 21:00, with a date to be determined," the regulator stated.
'Risk to Damage Credibility'
The regulator's announcement said: "Our probe found that the programme's lack of disclosure that the presenter's parent served in a post in the Hamas-run authority was substantially inaccurate.
"Consequently that the public did not have critical information which may have been extremely pertinent to their evaluation of the voice and the details he presented.
"Confidence is at the core of the connection between a television network and its viewers, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This error had the possibility to undermine the very considerable degrees of confidence that viewers would have placed in a BBC factual programme about the Israel-Gaza war."
The programme was pulled from iPlayer in last February after the presenter's family links came to light, and in July an corporation's own inquiry concluded it infringed the organization's editorial guidelines on accuracy.
A BBC spokesperson stated: "The regulator's decision is in agreement with the results of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on accuracy, which reflects clause 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will adhere to the directive as soon as the date and language are determined."
