The public service broadcaster engaged in a "significant breach" of media regulations by not revealing that the voice of a programme about the Gaza situation was the son of a Hamas administrator, according to UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The BBC's director general had earlier expressed regret, saying there had been "a serious error in relation to truthfulness".
The regulator has ordered the BBC to transmit a prime-time announcement about its decisions.
"Given this constitutes a major infringement of our rules, we are directing the broadcaster to transmit a statement of our determinations against it on BBC2 at 21:00, with a timing to be confirmed," the statement read.
'Potential to Damage Credibility'
The watchdog's statement stated: "The inquiry we conducted found that the film's lack of disclosure that the voice's father served in a position in the Hamas-run government was significantly deceptive.
"Consequently that the audience did not have vital facts which may have been highly relevant to their evaluation of the narrator and the content he presented.
"Credibility is at the core of the relationship between a television network and its viewers, especially for a national broadcasting corporation such as the public broadcaster.
"This failing had the possibility to damage the exceptionally strong levels of credibility that audiences would have placed in a BBC factual programme about the Gaza conflict."
The programme was removed from the online platform in the month of February after the presenter's personal associations were revealed, and in this past July an broadcaster's internal assessment found it violated the organization's journalistic standards on factual correctness.
A representative for the broadcaster stated: "The regulator's decision is in agreement with the conclusions of the corporation's inquiry, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on truthfulness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will comply with the directive as soon as the date and wording are finalised."
