The BBC engaged in a "serious breach" of media regulations by failing to disclose that the presenter of a programme about the Gaza situation was the child of a Hamas official, as determined by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The head of the BBC had earlier expressed regret, stating there had been "a major oversight in relation to accuracy".
Ofcom has directed the corporation to broadcast a evening statement about its findings.
"Since this amounts to a major infringement of our regulations, we are ordering the broadcaster to transmit a message of our findings against it on the BBC's second channel at 9pm, with a timing to be finalised," it said.
'Possibility to Erode Confidence'
The regulator's announcement said: "Our probe determined that the documentary's lack of disclosure that the voice's parent occupied a role in the Hamas-controlled administration was substantially inaccurate.
"Consequently that the public did not have vital facts which may have been extremely pertinent to their assessment of the voice and the content he presented.
"Credibility is at the core of the relationship between a media organization and its audience, particularly for a public service broadcaster such as the BBC.
"This error had the risk to damage the exceptionally strong amounts of confidence that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The film was removed from iPlayer in last February after the narrator's personal associations came to light, and in the month of July an broadcaster's internal assessment determined it infringed the broadcaster's content policies on accuracy.
A corporation official commented: "The regulator's decision is in agreement with the results of the corporation's inquiry, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We have apologised 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 determined."
