The British broadcaster engaged in a "significant breach" of broadcasting rules by not revealing that the presenter of a documentary about the Gaza situation was the son of a Hamas administrator, as determined by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a major oversight in relation to truthfulness".
The regulator has directed the corporation to air a evening statement about its findings.
"As this represents a major infringement of our code, we are instructing the broadcaster to broadcast a statement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be confirmed," the regulator stated.
'Possibility to Erode Credibility'
The regulator's announcement declared: "The inquiry we conducted concluded that the film's lack of disclosure that the voice's parent held a role in the Hamas-administered government was substantially inaccurate.
"Consequently that the audience did not have essential details which may have been highly relevant to their assessment of the presenter and the details he provided.
"Trust is at the core of the bond between a media organization and its viewers, especially for a public service broadcaster such as the BBC.
"This oversight had the potential to erode the exceptionally strong amounts of confidence that the public would have put in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was withdrawn from the online platform in last February after the boy's family links were revealed, and in July an broadcaster's internal assessment determined it infringed the broadcaster's journalistic standards on truthfulness.
A representative for the broadcaster said: "The authority's determination is in accordance with the findings of the internal assessment, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will comply with the sanction as soon as the schedule and wording are confirmed."
