The public service broadcaster engaged in a "serious breach" of industry standards by not revealing that the narrator of a documentary about Gaza was the son of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The head of the BBC had earlier expressed regret, noting there had been "a significant failing in relation to accuracy".
The regulator has directed the corporation to transmit a prime-time statement about its findings.
"As this represents a serious breach of our regulations, we are instructing the BBC to broadcast a statement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a date to be confirmed," the regulator stated.
'Potential to Damage Credibility'
The regulator's statement declared: "Our investigation found that the documentary's omission to reveal that the narrator's parent served in a position in the Hamas-run government was significantly deceptive.
"Consequently that the audience did not have vital facts which may have been extremely pertinent to their judgment of the presenter and the content he provided.
"Confidence is at the heart of the bond between a broadcaster and its viewers, especially for a state-funded media outlet such as the public broadcaster.
"This error had the potential to undermine the very considerable degrees of confidence that audiences would have placed in a BBC factual programme about the Gaza conflict."
The film was removed from iPlayer in the month of February after the presenter's family links came to light, and in the month of July an corporation's own inquiry concluded it violated the organization's editorial guidelines on accuracy.
A representative for the broadcaster stated: "The regulator's decision is in line with the results of Peter Johnston's review, that there was a major oversight in the documentary in relation to the broadcaster's journalistic policies on truthfulness, which reflects regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will comply with the directive as soon as the timing and wording are determined."
