The public service broadcaster committed a "serious breach" of broadcasting rules by omitting to mention that the narrator of a film about the Gaza situation was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An inquiry by Ofcom into the programme Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The BBC's director general had previously apologised, stating there had been "a significant failing in relation to accuracy".
The authority has ordered the corporation to air a peak-time statement about its conclusions.
"As this represents a major infringement of our regulations, we are directing the BBC to transmit a message of our conclusions against it on BBC2 at 9pm, with a timing to be determined," the regulator stated.
'Possibility to Undermine Confidence'
The regulator's announcement declared: "Our probe determined that the documentary's omission to reveal that the presenter's father held a position in the Hamas-run government was materially misleading.
"It meant that the public did not have vital facts which may have been extremely pertinent to their judgment of the presenter and the details he presented.
"Trust is at the center of the connection between a television network and its viewers, especially for a state-funded media outlet such as the BBC.
"This failing had the possibility to damage the very considerable levels of trust that audiences would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was pulled from the BBC's streaming service in the month of February after the boy's familial connections came to light, and in the month of July an broadcaster's internal assessment found it infringed the corporation's content policies on truthfulness.
A representative for the broadcaster commented: "The Ofcom ruling is in line with the results of the internal assessment, that there was a major oversight in the documentary in relation to the corporation's content standards on truthfulness, which corresponds to Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with the authority's determination in full. We will comply with the directive as soon as the timing and language are finalised."
