The British broadcaster committed a "significant breach" of broadcasting rules by failing to disclose that the narrator of a film about Gaza was the child of a Hamas official, as determined by regulatory body Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The BBC's director general had earlier expressed regret, saying there had been "a major oversight in relation to accuracy".
Ofcom has ordered the corporation to broadcast a peak-time declaration about its decisions.
"Given this constitutes a serious breach of our rules, we are directing the corporation to broadcast a message of our determinations against it on BBC2 at 9pm, with a schedule to be confirmed," the statement read.
'Possibility to Damage Trust'
The authority's statement said: "The inquiry we conducted determined that the documentary's lack of disclosure that the presenter's father occupied a post in the Hamas-controlled administration was significantly deceptive.
"It meant that the audience did not have critical information which may have been extremely pertinent to their judgment of the narrator and the content he shared.
"Credibility is at the core of the relationship between a broadcaster and its audience, particularly for a state-funded media outlet such as the BBC.
"This failing had the potential to undermine the very considerable degrees of trust that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was pulled from iPlayer in the month of February after the narrator's familial connections came to light, and in this past July an broadcaster's internal assessment concluded it breached the organization's editorial guidelines on accuracy.
A BBC spokesperson stated: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on accuracy, which aligns with Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with the authority's determination in complete. We will adhere to the directive as soon as the timing and wording are confirmed."
