The British broadcaster committed a "serious breach" of industry standards by omitting to mention that the presenter of a programme about Gaza was the son of a Hamas official, as determined by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The head of the BBC had previously apologised, noting there had been "a significant failing in relation to accuracy".
The regulator has ordered the corporation to broadcast a prime-time statement about its decisions.
"Given this constitutes a serious breach of our regulations, we are ordering the broadcaster to air a announcement of our conclusions against it on BBC2 at 21:00, with a date to be finalised," the statement read.
'Risk to Undermine Confidence'
The regulator's announcement declared: "Our probe found that the film's omission to reveal that the narrator's father served in a role in the Hamas-run authority was substantially inaccurate.
"It meant that the viewers did not have vital facts which may have been highly relevant to their judgment of the voice and the information he shared.
"Confidence is at the center of the relationship between a media organization and its viewers, notably for a public service broadcaster such as the public broadcaster.
"This oversight had the possibility to erode the very considerable levels of credibility that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
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 breached the organization's content policies on accuracy.
A corporation official stated: "The authority's determination is in accordance with the conclusions of the corporation's inquiry, that there was a significant failing in the documentary in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will comply with the sanction as soon as the date and language are confirmed."
