The public service broadcaster was found to have committed a "major breach" of industry standards by failing to disclose that the narrator of a documentary about the Gaza situation was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The regulator has directed the corporation to transmit a prime-time declaration about its decisions.
"As this represents a serious breach of our regulations, we are instructing the broadcaster to broadcast a statement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be determined," it said.
'Possibility to Damage Confidence'
The watchdog's announcement said: "Our probe found that the programme's omission to reveal that the presenter's father served in a post in the Hamas-run administration was significantly deceptive.
"This implied that the audience did not have vital facts which may have been very significant to their evaluation of the presenter and the details he presented.
"Credibility is at the heart of the connection between a broadcaster and its viewers, especially for a state-funded media outlet such as the public broadcaster.
"This oversight had the risk to damage the exceptionally strong degrees of credibility that the public would have placed in a BBC factual programme about the Gaza conflict."
The programme was removed from the BBC's streaming service in the month of February after the presenter's familial connections came to light, and in the month of July an broadcaster's internal assessment concluded it breached the corporation's content policies on factual correctness.
A corporation official said: "The Ofcom ruling is in accordance with the results of Peter Johnston's review, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with the regulator's ruling in full. We will adhere to the directive as soon as the timing and wording are finalised."
