The BBC was found to have committed a "serious breach" of media regulations by failing to disclose that the presenter of a documentary about the Gaza situation was the son of a Hamas representative, according to UK media regulator Ofcom.
An probe by the broadcasting watchdog into Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The head of the BBC had already issued an apology, noting there had been "a significant failing in relation to truthfulness".
The regulator has ordered the corporation to transmit a prime-time statement about its findings.
"Since this amounts to a serious breach of our rules, we are ordering the BBC to transmit a message of our determinations against it on BBC2 at 21:00, with a timing to be determined," the statement read.
'Potential to Damage Credibility'
The authority's report declared: "Our investigation found that the film's lack of disclosure that the narrator's father served in a position in the Hamas-run government was substantially inaccurate.
"It meant that the viewers did not have critical information which may have been very significant to their assessment of the narrator and the content he provided.
"Confidence is at the core of the relationship between a media organization and its audience, notably for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to undermine the very considerable degrees of confidence that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The programme was withdrawn from iPlayer in the month of February after the narrator's personal associations were revealed, and in this past July an corporation's own inquiry found it violated the corporation's content policies on truthfulness.
A corporation official stated: "The Ofcom ruling is in agreement with the conclusions of the corporation's inquiry, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on factual correctness, which reflects clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with Ofcom's decision in its entirety. We will follow the directive as soon as the schedule and language are confirmed."
