The BBC engaged in a "serious breach" of industry standards by not revealing that the presenter of a film about the Gaza conflict was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, saying there had been "a serious error in relation to factual correctness".
Ofcom has directed the corporation to transmit a evening statement about its conclusions.
"As this represents a serious breach of our regulations, we are instructing the broadcaster to broadcast a message of our findings against it on BBC Two at nine o'clock in the evening, with a schedule to be confirmed," it said.
'Risk to Damage Trust'
The watchdog's report declared: "Our investigation concluded that the programme's failure to disclose that the narrator's father served in a post in the Hamas-run government was significantly deceptive.
"This implied that the audience did not have critical information which may have been extremely pertinent to their judgment of the voice and the details he provided.
"Confidence is at the center of the relationship between a media organization and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This error had the possibility to erode the exceptionally strong amounts of trust that the public would have placed in a BBC factual programme about the Israel-Gaza war."
The film was withdrawn from the BBC's streaming service in last February after the presenter's familial connections came to light, and in this past July an corporation's own inquiry found it violated the organization's editorial guidelines on accuracy.
A corporation official commented: "The Ofcom ruling is in accordance with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on truthfulness, which reflects regulation 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with Ofcom's decision in full. We will comply with the sanction as soon as the timing and wording are confirmed."
