The public service broadcaster committed a "serious breach" of broadcasting rules by omitting to mention that the voice of a film about Gaza was the son of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, saying there had been "a major oversight in relation to accuracy".
The regulator has ordered the BBC to transmit a evening announcement about its decisions.
"Given this constitutes a significant violation of our rules, we are directing the broadcaster to transmit a message of our findings against it on BBC Two at 9pm, with a schedule to be confirmed," it said.
'Possibility to Erode Credibility'
The regulator's announcement said: "Our investigation determined that the film's failure to disclose that the narrator's parent held a post in the Hamas-controlled authority was significantly deceptive.
"This implied that the audience did not have vital facts which may have been highly relevant to their judgment of the voice and the information he provided.
"Credibility is at the core of the bond between a broadcaster and its viewers, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the risk to damage the exceptionally strong levels of confidence that audiences would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was pulled from the online platform in last February after the boy's family links emerged, and in the month of July an corporation's own inquiry concluded it violated the organization's content policies on factual correctness.
A BBC spokesperson stated: "The Ofcom ruling is in line 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 reflects clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the regulator's ruling in its entirety. We will adhere to the penalty as soon as the date and language are determined."
