The British broadcaster committed a "major breach" of broadcasting rules by omitting to mention that the narrator of a documentary about Gaza was the offspring of a Hamas representative, according to regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The BBC's director general had previously apologised, saying there had been "a serious error in relation to accuracy".
Ofcom has directed the corporation to broadcast a evening statement about its findings.
"As this represents a significant violation of our code, we are directing the broadcaster to broadcast a announcement of our determinations against it on BBC Two at nine o'clock in the evening, with a schedule to be determined," the regulator stated.
'Potential to Damage Credibility'
The watchdog's report stated: "Our probe determined that the documentary's omission to reveal that the presenter's father held a post in the Hamas-controlled government was substantially inaccurate.
"Consequently that the viewers did not have essential details which may have been extremely pertinent to their judgment of the voice and the content he provided.
"Trust is at the center of the bond between a broadcaster and its audience, especially for a national broadcasting corporation such as the BBC.
"This oversight had the possibility to damage the exceptionally strong levels of credibility that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was pulled from the online platform in last February after the narrator's familial connections were revealed, and in this past July an corporation's own inquiry determined it violated the corporation's content policies on factual correctness.
A representative for the broadcaster stated: "The authority's determination is in line with the conclusions of the internal assessment, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on truthfulness, which reflects regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the regulator's ruling in complete. We will follow the directive as soon as the timing and language are determined."
