The public service broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the presenter of a film about Gaza was the child of a Hamas official, according to British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a significant failing in relation to accuracy".
The regulator has instructed the BBC to air a prime-time declaration about its findings.
"As this represents a major infringement of our rules, we are ordering the broadcaster to air a statement of our determinations against it on BBC Two at 9pm, with a schedule to be determined," the statement read.
'Potential to Erode Trust'
The watchdog's report stated: "Our investigation found that the documentary's omission to reveal that the voice's parent served in a post in the Hamas-controlled administration was substantially inaccurate.
"This implied that the public did not have critical information which may have been very significant to their assessment of the presenter and the information he provided.
"Trust is at the heart of the relationship between a media organization and its viewers, notably for a national broadcasting corporation such as the BBC.
"This failing had the risk to erode the exceptionally strong degrees of credibility that viewers would have put in a BBC factual programme about the Gaza conflict."
The documentary was withdrawn from the online platform in the month of February after the presenter's personal associations came to light, and in this past July an internal BBC review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 organization's content policies on truthfulness.
A corporation official stated: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on accuracy, which aligns with Rule 2.2 of the regulator's media standards.
"We have apologised for this and we accept the regulator's ruling in full. We will comply with the directive as soon as the schedule and wording are determined."
