The British broadcaster engaged in a "serious breach" of industry standards by omitting to mention that the voice of a programme about Gaza was the son of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, stating there had been "a major oversight in relation to accuracy".
The regulator has ordered the broadcaster to air a prime-time announcement about its decisions.
"Since this amounts to a serious breach of our code, we are directing the broadcaster to broadcast a statement of our conclusions against it on BBC Two at nine o'clock in the evening, with a date to be determined," it said.
'Possibility to Undermine Credibility'
The authority's report declared: "The inquiry we conducted concluded that the programme's omission to reveal that the narrator's parent occupied a post in the Hamas-controlled authority was substantially inaccurate.
"Consequently that the audience did not have vital facts which may have been highly relevant to their evaluation of the narrator and the information he shared.
"Trust is at the center of the connection between a television network and its audience, notably for a national broadcasting corporation such as the BBC.
"This oversight had the risk to erode the significantly high levels of confidence that audiences would have invested in a factual film from the broadcaster about the Gaza conflict."
The film was pulled from the online platform in February after the narrator's family links emerged, and in the month of July an corporation's own inquiry concluded it violated the organization's content policies on factual correctness.
A corporation official said: "The Ofcom ruling is in agreement with the conclusions of the internal assessment, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept Ofcom's decision in its entirety. We will comply with the directive as soon as the date and wording are finalised."
