The British broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the voice of a documentary about Gaza was the offspring of a Hamas representative, according to British broadcasting authority Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has instructed the BBC to transmit a evening statement about its conclusions.
"As this represents a serious breach of our rules, we are ordering the BBC to broadcast a message of our conclusions against it on the BBC's second channel at 9pm, with a date to be determined," it said.
'Possibility to Undermine Confidence'
The authority's report declared: "The inquiry we conducted determined that the programme's omission to reveal that the narrator's male guardian occupied a role in the Hamas-run administration was substantially inaccurate.
"It meant that the audience did not have critical information which may have been extremely pertinent to their assessment of the narrator and the details he provided.
"Credibility is at the core of the bond between a media organization and its public, notably for a public service broadcaster such as the public broadcaster.
"This error had the potential to damage the significantly high levels of confidence that the public would have invested in a factual film from the broadcaster about the conflict in Gaza."
The film was withdrawn from the online platform in last February after the presenter's personal associations emerged, and in the month of July an broadcaster's internal assessment determined it infringed the organization's content policies on truthfulness.
A representative for the broadcaster commented: "The authority's determination is in accordance with the conclusions of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on truthfulness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept the authority's determination in its entirety. We will follow the sanction as soon as the schedule and wording are determined."
