The British broadcaster committed a "major breach" of media regulations by omitting to mention that the presenter of a programme about Gaza was the son of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The chief executive of the broadcaster had previously apologised, noting there had been "a serious error in relation to factual correctness".
The regulator has ordered the corporation to broadcast a evening statement about its conclusions.
"Since this amounts to a serious breach of our regulations, we are directing the corporation to air a statement of our findings against it on BBC2 at 21:00, with a timing to be confirmed," it said.
'Possibility to Undermine Confidence'
The authority's report stated: "Our probe determined that the documentary's failure to disclose that the narrator's parent held a position in the Hamas-run administration was significantly deceptive.
"It meant that the audience did not have vital facts which may have been highly relevant to their evaluation of the presenter and the details he provided.
"Confidence is at the heart of the bond between a television network and its public, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the risk to undermine the significantly high levels of credibility that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was pulled from the online platform in the month of February after the narrator's familial connections emerged, and in this past July an internal BBC review concluded it breached the broadcaster's editorial guidelines on factual correctness.
A representative for the broadcaster stated: "The authority's determination is in agreement with the findings of Peter Johnston's review, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the regulator's ruling in full. We will follow the sanction as soon as the schedule and wording are finalised."
