The public service broadcaster committed a "serious breach" of broadcasting rules by not revealing that the voice of a film about Gaza was the son of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The BBC's director general had previously apologised, stating there had been "a serious error in relation to truthfulness".
The regulator has ordered the broadcaster to broadcast a evening statement about its findings.
"As this represents a serious breach of our code, we are ordering the BBC to air a statement of our determinations against it on BBC Two at nine o'clock in the evening, with a schedule to be confirmed," the statement read.
'Risk to Undermine Credibility'
The watchdog's report said: "Our investigation found that the programme's omission to reveal that the voice's father occupied a position in the Hamas-administered government was significantly deceptive.
"This implied that the public did not have critical information which may have been highly relevant to their judgment of the narrator and the content he provided.
"Confidence is at the core of the connection between a television network and its audience, especially for a public service broadcaster such as the BBC.
"This failing had the risk to erode the exceptionally strong degrees of trust that viewers would have invested in a BBC factual programme about the Gaza conflict."
The film was removed from the online platform in February after the narrator's family links emerged, and in this past July an broadcaster's internal assessment determined it violated the organization's content policies on factual correctness.
A corporation official stated: "The regulator's decision is in line with the findings of the corporation's inquiry, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will adhere to the directive as soon as the schedule and language are finalised."
