The British broadcaster committed a "serious breach" of industry standards by omitting to mention that the presenter of a film about Gaza was the son of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a significant failing in relation to factual correctness".
The regulator has directed the BBC to air a peak-time statement about its conclusions.
"Given this constitutes a serious breach of our code, we are instructing the BBC to air a statement of our findings against it on the BBC's second channel at 9pm, with a date to be finalised," the regulator stated.
'Risk to Damage Credibility'
The watchdog's statement stated: "Our investigation found that the film's lack of disclosure that the presenter's parent served in a position in the Hamas-run authority was significantly deceptive.
"This implied that the audience did not have critical information which may have been very significant to their evaluation of the presenter and the details he presented.
"Confidence is at the core of the connection between a television network and its audience, notably for a state-funded media outlet such as the BBC.
"This error had the risk to damage the very considerable amounts of trust that viewers would have put in a BBC factual programme about the Israel-Gaza war."
The programme was removed from iPlayer in last February after the boy's personal associations came to light, and in the month of July an corporation's own inquiry concluded it violated the broadcaster's journalistic standards on factual correctness.
A corporation official said: "The Ofcom ruling is in line with the conclusions of the corporation's inquiry, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on truthfulness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the regulator's ruling in its entirety. We will follow the penalty as soon as the date and language are finalised."
