The BBC was found to have committed a "serious breach" of broadcasting rules by not revealing that the voice of a programme about Gaza was the child of a Hamas administrator, according to British broadcasting authority Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has found that the documentary was "substantially inaccurate".
The head of the BBC had earlier expressed regret, saying there had been "a serious error in relation to truthfulness".
Ofcom has instructed the corporation to transmit a prime-time statement about its decisions.
"Since this amounts to a serious breach of our rules, we are ordering the broadcaster to air a announcement of our conclusions against it on BBC Two at 21:00, with a timing to be determined," the regulator stated.
'Risk to Damage Credibility'
The authority's report declared: "Our investigation found that the programme's omission to reveal that the voice's father occupied a position in the Hamas-controlled government was significantly deceptive.
"Consequently that the public did not have vital facts which may have been extremely pertinent to their judgment of the narrator and the details he provided.
"Confidence is at the core of the relationship between a television network and its viewers, particularly for a state-funded media outlet such as the public broadcaster.
"This oversight had the risk to damage the very considerable amounts of trust that audiences would have invested in a documentary produced by the BBC about the Israel-Gaza war."
The film was removed from the online platform in February after the presenter's familial connections emerged, and in the month of July an internal BBC review determined it infringed the broadcaster's content policies on truthfulness.
A corporation official stated: "The authority's determination is in line with the results of the corporation's inquiry, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on truthfulness, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the regulator's ruling in its entirety. We will adhere to the directive as soon as the timing and wording are finalised."
