The BBC committed a "serious breach" of media regulations by failing to disclose that the presenter of a film about the Gaza situation was the offspring of a Hamas representative, as ruled by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the documentary was "materially misleading".
The head of the BBC had previously apologised, noting there had been "a major oversight in relation to truthfulness".
The authority has directed the broadcaster to transmit a evening statement about its decisions.
"Given this constitutes a serious breach of our rules, we are directing the corporation to broadcast a statement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be confirmed," it said.
'Possibility to Undermine Trust'
The regulator's report declared: "Our probe found that the programme's lack of disclosure that the voice's parent served in a position in the Hamas-run authority was significantly deceptive.
"This implied that the viewers did not have essential details which may have been very significant to their assessment of the narrator and the information he presented.
"Credibility is at the heart of the bond between a media organization and its audience, particularly for a public service broadcaster such as the BBC.
"This error had the possibility to erode the significantly high amounts of confidence that viewers would have invested in a BBC factual programme about the Gaza conflict."
The film was removed from the online platform in the month of February after the boy's familial connections emerged, and in this past July an internal BBC review determined it violated the organization's journalistic standards on truthfulness.
A corporation official said: "The regulator's decision is in line with the conclusions of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on truthfulness, which reflects regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with the authority's determination in complete. We will follow the sanction as soon as the date and wording are determined."
