The British broadcaster committed a "serious breach" of broadcasting rules by omitting to mention that the voice of a programme about the Gaza situation was the son 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 found that the documentary was "substantially inaccurate".
The head of the BBC had previously apologised, noting there had been "a serious error in relation to truthfulness".
The authority has instructed the BBC to transmit a prime-time announcement about its conclusions.
"As this represents a serious breach of our rules, we are directing the BBC to air a statement of our conclusions against it on BBC2 at nine o'clock in the evening, with a schedule to be finalised," the regulator stated.
'Risk to Damage Credibility'
The watchdog's report declared: "The inquiry we conducted concluded that the programme's omission to reveal that the narrator's parent held a post in the Hamas-controlled administration was significantly deceptive.
"Consequently that the audience did not have critical information which may have been highly relevant to their judgment of the narrator and the content he presented.
"Trust is at the core of the connection between a television network and its audience, notably for a state-funded media outlet such as the public broadcaster.
"This failing had the potential to undermine the significantly high degrees of trust that audiences would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The documentary was withdrawn from the online platform in the month of February after the presenter's familial connections were revealed, and in the month of July an corporation's own inquiry found it infringed the broadcaster's editorial guidelines on accuracy.
A representative for the broadcaster said: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to regulation 2.2 of the regulator's media standards.
"We have apologised for this and we agree with Ofcom's decision in complete. We will follow the sanction as soon as the timing and wording are confirmed."
