The British broadcaster was found to have committed a "major breach" of broadcasting rules by not revealing that the presenter of a documentary about the Gaza conflict was the son of a Hamas official, as determined by British broadcasting authority Ofcom.
An inquiry by Ofcom into Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a major oversight in relation to truthfulness".
The regulator has instructed the broadcaster to transmit a prime-time statement about its decisions.
"As this represents a serious breach of our code, we are instructing the broadcaster to air a message of our findings against it on the BBC's second channel at 21:00, with a timing to be confirmed," the regulator stated.
'Potential to Damage Confidence'
The regulator's report stated: "Our probe determined that the programme's omission to reveal that the voice's male guardian occupied a position in the Hamas-controlled authority was materially misleading.
"This implied that the public did not have critical information which may have been very significant to their assessment of the voice and the information he provided.
"Credibility is at the heart of the bond between a broadcaster and its audience, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the risk to erode the exceptionally strong amounts of confidence that viewers would have put in a BBC factual programme about the Israel-Gaza war."
The documentary was pulled from the online platform in the month of February after the presenter's personal associations came to light, and in this past July an internal BBC review concluded it breached the corporation's content policies on accuracy.
A representative for the broadcaster stated: "The authority's determination is in agreement with the results 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 aligns with regulation 2.2 of the regulator's media standards.
"We have apologised for this and we agree with the regulator's ruling in full. We will comply with the directive as soon as the date and language are determined."
