The public service broadcaster engaged in a "serious breach" of broadcasting rules by failing to disclose that the presenter of a film about the Gaza situation was the offspring of a Hamas administrator, according to UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to factual correctness".
Ofcom has ordered the corporation to air a evening declaration about its conclusions.
"Since this amounts to a significant violation of our code, we are ordering the BBC to broadcast a announcement of our determinations against it on the BBC's second channel at 21:00, with a schedule to be confirmed," it said.
'Potential to Erode Confidence'
The watchdog's announcement stated: "Our investigation determined that the film's failure to disclose that the voice's parent held a role in the Hamas-administered authority was significantly deceptive.
"It meant that the audience did not have vital facts which may have been extremely pertinent to their evaluation of the narrator and the content he provided.
"Trust is at the heart of the connection between a media organization and its audience, notably for a national broadcasting corporation such as the public broadcaster.
"This failing had the possibility to damage the very considerable levels of trust that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The documentary was removed from the BBC's streaming service in the month of February after the presenter's personal associations were revealed, and in this past July an corporation's own inquiry found it violated the corporation's journalistic standards on factual correctness.
A representative for the broadcaster stated: "The Ofcom ruling is in line with the conclusions of the internal assessment, that there was a major oversight in the programme in relation to the corporation's content standards on factual correctness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the regulator's ruling in its entirety. We will adhere to the directive as soon as the schedule and wording are determined."
