The BBC was found to have committed a "significant breach" of industry standards by omitting to mention that the voice of a documentary about the Gaza situation was the son of a Hamas representative, as determined by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The head of the BBC had already issued an apology, noting there had been "a significant failing in relation to accuracy".
The authority has directed the corporation to transmit a evening declaration about its decisions.
"Since this amounts to a major infringement of our rules, we are directing the broadcaster to air a statement of our conclusions against it on the BBC's second channel at 21:00, with a schedule to be finalised," the regulator stated.
'Possibility to Damage Credibility'
The watchdog's announcement declared: "The inquiry we conducted concluded that the film's lack of disclosure that the presenter's parent served in a position in the Hamas-controlled administration was substantially inaccurate.
"Consequently that the public did not have critical information which may have been very significant to their assessment of the presenter and the details he presented.
"Trust is at the center of the connection between a broadcaster and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This failing had the potential to erode the significantly high degrees of trust that viewers would have invested in a documentary produced by the BBC about the conflict in Gaza."
The programme was pulled from the BBC's streaming service in the month of February after the narrator's personal associations came to light, and in the month of July an internal BBC review determined it breached the corporation's journalistic standards on truthfulness.
A corporation official said: "The regulator's decision is in agreement with the results of the corporation's inquiry, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on truthfulness, which aligns with clause 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in full. We will adhere to the penalty as soon as the timing and wording are finalised."
