The British broadcaster was found to have committed a "major breach" of media regulations by failing to disclose that the narrator of a film about the Gaza situation was the son of a Hamas administrator, according to regulatory body Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, noting there had been "a major oversight in relation to truthfulness".
Ofcom has directed the broadcaster to transmit a evening announcement about its decisions.
"As this represents a major infringement of our regulations, we are directing the BBC to air a message of our findings against it on the BBC's second channel at nine o'clock in the evening, with a timing to be finalised," the statement read.
'Potential to Erode Confidence'
The watchdog's report declared: "Our probe determined that the programme's omission to reveal that the voice's father occupied a position in the Hamas-administered government was materially misleading.
"This implied that the audience did not have critical information which may have been extremely pertinent to their assessment of the narrator and the details he provided.
"Confidence is at the heart of the relationship between a broadcaster and its public, particularly for a state-funded media outlet such as the public broadcaster.
"This failing had the potential to erode the very considerable levels of confidence that the public would have invested in a documentary produced by the BBC about the conflict in Gaza."
The film was removed 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 determined it violated the broadcaster's journalistic standards on truthfulness.
A representative for the broadcaster said: "The authority's determination is in line with the results of Peter Johnston's review, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on accuracy, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with the regulator's ruling in full. We will follow the directive as soon as the timing and wording are confirmed."
