The public service broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the narrator of a programme about the Gaza situation was the son of a Hamas administrator, according to UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The BBC's director general had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The regulator has ordered the corporation to air a evening statement about its findings.
"As this represents a significant violation of our regulations, we are ordering the broadcaster to air a announcement of our determinations against it on BBC Two at 9pm, with a timing to be confirmed," the regulator stated.
'Risk to Damage Credibility'
The authority's statement declared: "Our probe found that the film's omission to reveal that the narrator's male guardian held a position in the Hamas-controlled government was substantially inaccurate.
"This implied that the public did not have vital facts which may have been highly relevant to their evaluation of the narrator and the details he provided.
"Credibility is at the center of the relationship between a broadcaster and its viewers, notably for a public service broadcaster such as the public broadcaster.
"This error had the potential to undermine the very considerable amounts of trust that viewers would have invested in a documentary produced by the BBC about the conflict in Gaza."
The programme was pulled from iPlayer in the month of February after the presenter's family links emerged, and in the month of July an corporation's own inquiry determined it violated the broadcaster's journalistic standards on factual correctness.
A corporation official stated: "The authority's determination is in line with the findings of Peter Johnston's review, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with the regulator's ruling in complete. We will follow the penalty as soon as the timing and language are confirmed."
