The public service broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the presenter of a film about the Gaza situation was the son of a Hamas official, according to UK media regulator Ofcom.
An inquiry by Ofcom into the programme Gaza: How to Survive a Warzone has found that the documentary was "materially misleading".
The chief executive of the broadcaster had already issued an apology, noting there had been "a significant failing in relation to truthfulness".
Ofcom has directed the broadcaster to air a evening statement about its decisions.
"As this represents a major infringement of our code, we are instructing the BBC to air a statement of our findings against it on BBC Two at 9pm, with a date to be determined," the statement read.
'Risk to Erode Trust'
The authority's announcement said: "Our investigation concluded that the documentary's omission to reveal that the narrator's parent held a position in the Hamas-run government was substantially inaccurate.
"Consequently that the viewers did not have critical information which may have been very significant to their evaluation of the presenter and the details he provided.
"Credibility is at the core of the bond between a television network and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the possibility to undermine the very considerable amounts of confidence that the public would have invested 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 personal associations emerged, and in the month of July an internal BBC review determined it violated the broadcaster's journalistic standards on factual correctness.
A BBC spokesperson stated: "The regulator's decision is in line with the findings of Peter Johnston's review, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on factual correctness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in complete. We will adhere to the penalty as soon as the schedule and wording are determined."
