The British broadcaster was found to have committed a "major breach" of industry standards by failing to disclose that the voice of a film about the Gaza situation was the son of a Hamas administrator, as determined by UK media regulator Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, stating there had been "a significant failing in relation to truthfulness".
The authority has directed the broadcaster to air a evening statement about its findings.
"As this represents a significant violation of our rules, we are instructing the BBC to transmit a statement of our conclusions against it on BBC2 at nine o'clock in the evening, with a date to be confirmed," the regulator stated.
'Potential to Erode Confidence'
The regulator's announcement said: "The inquiry we conducted determined that the programme's failure to disclose that the narrator's parent occupied a position in the Hamas-controlled government was materially misleading.
"It meant that the public did not have critical information which may have been highly relevant to their judgment of the presenter and the information he presented.
"Credibility is at the center of the connection between a television network and its viewers, especially for a state-funded media outlet such as the public broadcaster.
"This failing had the potential to erode the very considerable levels of confidence that audiences would have placed in a factual film from the broadcaster about the Gaza conflict."
The film was withdrawn from the online platform in February after the narrator's family links were revealed, and in this past July an internal BBC review concluded it breached the broadcaster's content policies on factual correctness.
A representative for the broadcaster stated: "The Ofcom ruling is in line with the conclusions of the corporation's inquiry, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on accuracy, which reflects clause 2.2 of the regulator's media standards.
"We have apologised for this and we agree with the regulator's ruling in complete. We will comply with the sanction as soon as the date and wording are confirmed."
