The BBC engaged in a "significant breach" of media regulations by omitting to mention that the narrator of a film about the Gaza situation was the offspring of a Hamas representative, as determined by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The head of the BBC had already issued an apology, stating there had been "a major oversight in relation to truthfulness".
The regulator has instructed the BBC to broadcast a evening declaration about its conclusions.
"Given this constitutes a major infringement of our rules, we are directing the corporation to air a statement of our determinations against it on the BBC's second channel at 9pm, with a date to be confirmed," the statement read.
'Potential to Undermine Credibility'
The watchdog's statement declared: "The inquiry we conducted found that the documentary's omission to reveal that the voice's male guardian held a position in the Hamas-administered administration was substantially inaccurate.
"It meant that the public did not have vital facts which may have been very significant to their assessment of the presenter and the content he provided.
"Credibility is at the heart of the connection between a television network and its audience, particularly for a state-funded media outlet such as the public broadcaster.
"This oversight had the possibility to damage the exceptionally strong degrees of trust that the public would have placed in a BBC factual programme about the conflict in Gaza."
The programme was removed from iPlayer in February after the narrator's personal associations were revealed, and in the month of July an corporation's own inquiry found it violated the corporation's journalistic standards on accuracy.
A BBC spokesperson stated: "The regulator's decision is in agreement with the results of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with the authority's determination in full. We will comply with the directive as soon as the timing and language are finalised."
