The British broadcaster was found to have committed a "serious breach" of media regulations by failing to disclose that the presenter of a programme about the Gaza conflict was the offspring of a Hamas representative, as determined by British broadcasting authority Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to accuracy".
Ofcom has ordered the corporation to broadcast a evening statement about its findings.
"As this represents a serious breach of our regulations, we are ordering the corporation to transmit a message of our findings against it on the BBC's second channel at 9pm, with a date to be determined," it said.
'Risk to Damage Confidence'
The watchdog's report stated: "Our probe concluded that the programme's omission to reveal that the presenter's father held a position in the Hamas-controlled government was materially misleading.
"This implied that the viewers did not have vital facts which may have been highly relevant to their evaluation of the presenter and the details he provided.
"Credibility is at the heart of the relationship between a media organization and its public, notably for a public service broadcaster such as the public broadcaster.
"This error had the potential to undermine the significantly high amounts of credibility that the public would have put in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was removed from the online platform in February after the narrator's family links were revealed, and in this past July an corporation's own inquiry determined it breached the broadcaster's content policies on truthfulness.
A representative for the broadcaster stated: "The regulator's decision is in accordance with the conclusions of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on accuracy, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with the regulator's ruling in full. We will adhere to the penalty as soon as the schedule and wording are finalised."
