The BBC engaged in a "major breach" of industry standards by failing to disclose that the presenter of a documentary about the Gaza conflict was the child of a Hamas administrator, as ruled by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has found that the documentary was "materially misleading".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to accuracy".
The regulator has ordered the broadcaster to transmit a peak-time statement about its findings.
"As this represents a serious breach of our code, we are ordering the corporation to air a message of our conclusions against it on BBC Two at nine o'clock in the evening, with a date to be finalised," it said.
'Possibility to Erode Credibility'
The regulator's announcement declared: "The inquiry we conducted found that the documentary's omission to reveal that the presenter's father occupied a role in the Hamas-controlled government was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been highly relevant to their judgment of the voice and the content he shared.
"Confidence is at the heart of the relationship between a television network and its public, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the potential to erode the exceptionally strong levels of credibility that the public would have invested in a BBC factual programme about the Israel-Gaza war."
The film was withdrawn from the online platform in the month of February after the boy's familial connections were revealed, and in the month of July an broadcaster's internal assessment concluded it breached the organization's journalistic standards on accuracy.
A representative for the broadcaster commented: "The regulator's decision is in agreement with the findings of the internal assessment, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on truthfulness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we agree with the regulator's ruling in full. We will follow the directive as soon as the timing and language are confirmed."
