The BBC committed a "major breach" of media regulations by failing to disclose that the voice of a programme about the Gaza situation was the son of a Hamas administrator, as determined by regulatory body Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The BBC's director general had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The authority has ordered the corporation to air a evening statement about its conclusions.
"Given this constitutes a major infringement of our rules, we are instructing the broadcaster to transmit a message of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a timing to be confirmed," the regulator stated.
'Possibility to Erode Credibility'
The regulator's statement stated: "Our probe concluded that the documentary's lack of disclosure that the voice's father occupied a post in the Hamas-run administration was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been extremely pertinent to their evaluation of the voice and the content he shared.
"Credibility is at the heart of the connection between a broadcaster and its audience, especially for a public service broadcaster such as the BBC.
"This oversight had the possibility to damage the very considerable amounts of credibility that audiences would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was removed from iPlayer in the month of February after the presenter's personal associations were revealed, and in the month of July an broadcaster's internal assessment concluded it violated the organization's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The regulator's decision is in accordance with the conclusions of the internal assessment, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on truthfulness, which aligns with regulation 2.2 of the regulator's media standards.
"We expressed regret for this and we accept the authority's determination in complete. We will follow the sanction as soon as the date and language are finalised."
