The public service broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the presenter of a film about the Gaza situation was the child of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The BBC's director general had already issued an apology, noting there had been "a significant failing in relation to accuracy".
The regulator has directed the broadcaster to broadcast a peak-time statement about its findings.
"Given this constitutes a serious breach of our code, we are ordering the broadcaster to air a statement of our findings against it on BBC2 at 21:00, with a date to be confirmed," the regulator stated.
'Possibility to Erode Trust'
The authority's report declared: "Our probe determined that the documentary's omission to reveal that the voice's parent held a role in the Hamas-administered government was materially misleading.
"This implied that the viewers did not have vital facts which may have been highly relevant to their evaluation of the presenter and the information he provided.
"Trust is at the center of the relationship between a television network and its audience, notably for a national broadcasting corporation such as the BBC.
"This error had the possibility to damage the exceptionally strong degrees of credibility that viewers would have placed in a BBC factual programme about the conflict in Gaza."
The film was withdrawn from the online platform in last February after the presenter's familial connections came to light, and in this past July an corporation's own inquiry concluded it violated the broadcaster's journalistic standards on factual correctness.
A corporation official stated: "The authority's determination is in line with the conclusions of the corporation's inquiry, that there was a significant failing in the documentary in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will adhere to the directive as soon as the timing and wording are confirmed."
