The British broadcaster engaged in a "major breach" of media regulations by omitting to mention that the presenter of a documentary about the Gaza situation was the child of a Hamas representative, as determined by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The head of the BBC had earlier expressed regret, saying there had been "a serious error in relation to truthfulness".
The authority has ordered the BBC to transmit a evening statement about its conclusions.
"Since this amounts to a major infringement of our code, we are instructing the broadcaster to air a announcement of our findings against it on BBC Two at 9pm, with a timing to be finalised," the statement read.
'Potential to Damage Credibility'
The regulator's announcement declared: "Our investigation concluded that the programme's omission to reveal that the narrator's male guardian served in a role in the Hamas-administered administration was materially misleading.
"Consequently that the audience did not have vital facts which may have been very significant to their judgment of the narrator and the information he presented.
"Credibility is at the core of the connection between a broadcaster and its public, particularly for a state-funded media outlet such as the BBC.
"This error had the risk to erode the significantly high levels of confidence that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The film was removed from the online platform in February after the boy's personal associations emerged, and in this past July an broadcaster's internal assessment found it violated the organization's content policies on accuracy.
A representative for the broadcaster said: "The Ofcom ruling is in accordance with the conclusions of the corporation's inquiry, that there was a significant failing in the film in relation to the corporation's content standards on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in complete. We will comply with the sanction as soon as the schedule and wording are determined."
