The British broadcaster was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the presenter of a programme about Gaza was the son of a Hamas official, according to British broadcasting authority Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, saying there had been "a serious error in relation to accuracy".
The regulator has instructed the broadcaster to broadcast a evening statement about its decisions.
"As this represents a serious breach of our regulations, we are instructing the broadcaster to broadcast a statement of our findings against it on BBC2 at 9pm, with a timing to be confirmed," the regulator stated.
'Potential to Undermine Credibility'
The authority's announcement said: "Our investigation determined that the programme's lack of disclosure that the voice's parent occupied a post in the Hamas-run government was materially misleading.
"It meant that the audience did not have vital facts which may have been highly relevant to their judgment of the narrator and the information he presented.
"Confidence is at the center of the connection between a broadcaster and its audience, especially for a national broadcasting corporation such as the public broadcaster.
"This failing had the potential to damage the exceptionally strong amounts of confidence that the public would have invested in a factual film from the broadcaster about the conflict in Gaza."
The programme was pulled from the BBC's streaming service in February after the presenter's personal associations emerged, and in the month of July an corporation's own inquiry concluded it violated the broadcaster's content policies on truthfulness.
A BBC spokesperson commented: "The regulator's decision is in line with the findings of the internal assessment, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on accuracy, which aligns with clause 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with the authority's determination in full. We will comply with the sanction as soon as the timing and wording are finalised."
