The British broadcaster engaged in a "significant breach" of industry standards by failing to disclose that the voice of a documentary about Gaza was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, noting there had been "a major oversight in relation to truthfulness".
The regulator has directed the corporation to air a evening declaration about its conclusions.
"Since this amounts to a major infringement of our regulations, we are instructing the BBC to broadcast a announcement of our findings against it on BBC Two at nine o'clock in the evening, with a timing to be finalised," the statement read.
'Potential to Damage Confidence'
The regulator's report stated: "Our probe determined that the documentary's omission to reveal that the voice's parent held a role in the Hamas-run authority was materially misleading.
"It meant that the audience did not have vital facts which may have been highly relevant to their judgment of the narrator and the information he presented.
"Credibility is at the heart of the relationship between a broadcaster and its viewers, especially for a state-funded media outlet such as the BBC.
"This error had the risk to damage the exceptionally strong amounts of credibility that the public would have put in a factual film from the broadcaster about the conflict in Gaza."
The documentary was pulled from iPlayer in last February after the presenter's familial connections came to light, and in this past July an corporation's own inquiry found it breached the corporation's content policies on truthfulness.
A corporation official stated: "The authority's determination is in agreement with the conclusions of the internal assessment, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with clause 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with Ofcom's decision in its entirety. We will comply with the directive as soon as the timing and wording are finalised."
