The BBC engaged in a "major breach" of broadcasting rules by omitting to mention that the voice of a documentary about Gaza was the son of a Hamas official, as ruled by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had already issued an apology, saying there had been "a significant failing in relation to truthfulness".
The authority has directed the corporation to air a evening declaration about its decisions.
"Given this constitutes a serious breach of our rules, we are directing the BBC to air a statement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be determined," the regulator stated.
'Possibility to Damage Credibility'
The regulator's statement said: "Our probe determined that the film's failure to disclose that the voice's father served in a position in the Hamas-controlled administration was substantially inaccurate.
"Consequently that the public did not have vital facts which may have been very significant to their evaluation of the presenter and the details he presented.
"Confidence is at the core of the connection between a television network and its audience, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to damage the exceptionally strong degrees of trust that the public would have placed in a documentary produced by the BBC about the conflict in Gaza."
The film was pulled from the BBC's streaming service in February after the boy's personal associations were revealed, and in this past July an broadcaster's internal assessment found it breached the corporation's content policies on accuracy.
A corporation official stated: "The Ofcom ruling is in accordance with the results of the corporation's inquiry, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on accuracy, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we comply with Ofcom's decision in full. We will adhere to the penalty as soon as the date and wording are finalised."
