The public service broadcaster was found to have committed a "serious breach" of broadcasting rules by not revealing that the presenter of a film about Gaza was the son of a Hamas official, according to British broadcasting authority Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The chief executive of the broadcaster had previously apologised, saying there had been "a major oversight in relation to factual correctness".
Ofcom has instructed the BBC to transmit a evening statement about its conclusions.
"As this represents a significant violation of our rules, we are ordering the corporation to air a statement of our determinations against it on BBC Two at nine o'clock in the evening, with a timing to be determined," the statement read.
'Risk to Undermine Trust'
The regulator's report declared: "Our investigation found that the programme's lack of disclosure that the voice's parent occupied a role in the Hamas-controlled authority was significantly deceptive.
"Consequently that the audience did not have critical information which may have been extremely pertinent to their judgment of the presenter and the content he shared.
"Credibility is at the heart of the connection between a media organization and its audience, especially for a public service broadcaster such as the public broadcaster.
"This failing had the potential to damage the exceptionally strong amounts of confidence that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was pulled from the BBC's streaming service in the month of February after the presenter's family links came to light, and in the month of July an internal BBC review determined it violated the corporation's journalistic standards on factual correctness.
A representative for the broadcaster said: "The Ofcom ruling is in line with the results of the internal assessment, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which reflects Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will comply with the sanction as soon as the schedule and language are confirmed."
