The public service broadcaster engaged in a "serious breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza situation was the son of a Hamas representative, as determined by UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a serious error in relation to truthfulness".
The regulator has ordered the broadcaster to air a peak-time declaration about its findings.
"As this represents a major infringement of our regulations, we are ordering the broadcaster to transmit a statement of our conclusions against it on BBC Two at 21:00, with a schedule to be confirmed," the regulator stated.
'Possibility to Undermine Confidence'
The watchdog's statement said: "The inquiry we conducted found that the documentary's omission to reveal that the presenter's male guardian held a post in the Hamas-controlled authority was materially misleading.
"This implied that the public did not have critical information which may have been very significant to their judgment of the narrator and the details he provided.
"Confidence is at the center of the connection between a broadcaster and its audience, notably for a public service broadcaster such as the public broadcaster.
"This failing had the potential to erode the exceptionally strong levels of credibility that audiences would have put in a factual film from the broadcaster about the Gaza conflict."
The documentary was pulled from the BBC's streaming service in February after the presenter's familial connections came to light, and in the month of July an corporation's own inquiry found it infringed the corporation's journalistic standards on factual correctness.
A BBC spokesperson commented: "The regulator's decision is in line with the conclusions of the internal assessment, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on accuracy, which reflects Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with the authority's determination in its entirety. We will follow the directive as soon as the timing and wording are confirmed."
