The BBC was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the presenter of a film about the Gaza conflict was the child of a Hamas official, as ruled by British broadcasting authority Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The head of the BBC had previously apologised, noting there had been "a significant failing in relation to truthfulness".
The authority has directed the broadcaster to transmit a peak-time statement about its findings.
"Given this constitutes a significant violation of our rules, we are ordering the broadcaster to transmit a message of our determinations against it on BBC2 at 21:00, with a schedule to be confirmed," it said.
'Possibility to Damage Confidence'
The authority's statement said: "The inquiry we conducted determined that the programme's failure to disclose that the presenter's parent occupied a post in the Hamas-controlled government was significantly deceptive.
"Consequently that the viewers did not have critical information which may have been highly relevant to their judgment of the voice and the content he shared.
"Confidence is at the heart of the bond between a television network and its public, particularly for a state-funded media outlet such as the BBC.
"This failing had the potential to erode the significantly high amounts of confidence that audiences would have invested in a BBC factual programme about the Israel-Gaza war."
The film was removed from iPlayer in February after the boy's family links were revealed, and in this past July an broadcaster's internal assessment concluded it infringed the corporation's journalistic standards on accuracy.
A representative for the broadcaster stated: "The authority's determination is in accordance with the findings of Peter Johnston's review, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the authority's determination in its entirety. We will comply with the directive as soon as the timing and wording are determined."
