The public service broadcaster committed a "major breach" of industry standards by failing to disclose that the narrator of a programme about the Gaza conflict was the son of a Hamas representative, as determined by British broadcasting authority Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded 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 truthfulness".
The authority has instructed the broadcaster to air a peak-time statement about its conclusions.
"Given this constitutes a significant violation of our regulations, we are directing the broadcaster to air a message of our determinations against it on BBC Two at nine o'clock in the evening, with a schedule to be confirmed," the regulator stated.
'Possibility to Damage Trust'
The authority's announcement said: "Our investigation concluded that the programme's failure to disclose that the presenter's father occupied a role in the Hamas-administered government was substantially inaccurate.
"It meant that the viewers did not have vital facts which may have been highly relevant to their evaluation of the narrator and the content he presented.
"Credibility is at the heart of the relationship between a television network and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This oversight had the possibility to damage the very considerable degrees of trust that audiences would have invested in a BBC factual programme about the conflict in Gaza."
The film was removed from the online platform in the month of February after the boy's familial connections were revealed, and in this past July an corporation's own inquiry found it violated the organization's editorial guidelines on factual correctness.
A corporation official commented: "The Ofcom ruling is in line with the conclusions of the corporation's inquiry, that there was a significant failing in the film in relation to the corporation's content standards on factual correctness, which corresponds to regulation 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with the authority's determination in its entirety. We will comply with the directive as soon as the schedule and wording are determined."
