The public service broadcaster committed a "significant breach" of broadcasting rules by omitting to mention that the presenter of a documentary about the Gaza situation was the son of a Hamas official, as determined by UK media regulator Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The head of the BBC had earlier expressed regret, noting there had been "a major oversight in relation to truthfulness".
The authority has ordered the broadcaster to transmit a peak-time declaration about its decisions.
"Since this amounts to a major infringement of our code, we are ordering the corporation to air a announcement of our conclusions against it on the BBC's second channel at 9pm, with a date to be determined," the regulator stated.
'Possibility to Damage Trust'
The regulator's statement declared: "Our investigation found that the documentary's failure to disclose that the presenter's parent occupied a role in the Hamas-controlled government was substantially inaccurate.
"This implied that the viewers did not have essential details which may have been highly relevant to their evaluation of the presenter and the details he shared.
"Trust is at the heart of the connection between a media organization 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 levels of confidence that viewers would have placed in a factual film from the broadcaster about the Gaza conflict."
The film was removed from the BBC's streaming service in last February after the boy's personal associations came to light, and in July an internal BBC review determined it violated the organization's journalistic standards on truthfulness.
A BBC spokesperson said: "The regulator's decision is in agreement with the findings of the corporation's inquiry, that there was a major oversight in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with Ofcom's decision in full. We will follow the directive as soon as the date and language are finalised."
