The public service broadcaster engaged in a "significant breach" of media regulations by failing to disclose that the voice of a documentary about Gaza was the son of a Hamas official, as ruled by British broadcasting authority Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The head of the BBC had earlier expressed regret, stating there had been "a significant failing in relation to truthfulness".
The authority has directed the broadcaster to air a prime-time declaration about its decisions.
"Given this constitutes a serious breach of our regulations, we are directing the corporation to air a message of our conclusions against it on BBC2 at 21:00, with a schedule to be finalised," the statement read.
'Possibility to Undermine Credibility'
The authority's announcement declared: "Our investigation found that the documentary's failure to disclose that the presenter's male guardian occupied a role in the Hamas-run administration was materially misleading.
"This implied that the public did not have essential details which may have been very significant to their assessment of the narrator and the information he shared.
"Trust is at the core of the connection between a media organization and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the risk to damage the very considerable levels of confidence that viewers would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was pulled from the online platform in the month of February after the presenter's family links emerged, and in the month of July an internal BBC review determined it violated the broadcaster's content policies on truthfulness.
A BBC spokesperson stated: "The regulator's decision is in line with the conclusions of Peter Johnston's review, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which corresponds to Rule 2.2 of the regulator's media standards.
"We have apologised for this and we agree with the authority's determination in its entirety. We will comply with the directive as soon as the schedule and wording are confirmed."
