The British broadcaster committed a "significant breach" of industry standards by omitting to mention that the presenter of a film about the Gaza conflict was the child of a Hamas administrator, according to British broadcasting authority Ofcom.
An inquiry by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the programme was "materially misleading".
The BBC's director general had previously apologised, saying there had been "a serious error in relation to accuracy".
The authority has directed the broadcaster to air a evening declaration about its findings.
"Since this amounts to a major infringement of our regulations, we are ordering the BBC to transmit a message of our conclusions against it on BBC2 at 9pm, with a date to be confirmed," the statement read.
'Risk to Undermine Credibility'
The watchdog's announcement said: "Our investigation determined that the programme's failure to disclose that the voice's male guardian held a role in the Hamas-run government was significantly deceptive.
"Consequently that the public did not have essential details which may have been highly relevant to their assessment of the narrator and the information he shared.
"Confidence is at the center of the relationship between a media organization and its public, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the risk to damage the significantly high amounts of trust that the public would have invested in a BBC factual programme about the conflict in Gaza."
The film was withdrawn from the online platform in the month of February after the narrator's family links emerged, and in this past July an corporation's own inquiry found it violated the organization's content policies on factual correctness.
A corporation official stated: "The regulator's decision is in accordance with the findings of the internal assessment, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to regulation 2.2 of the regulator's media standards.
"We have apologised for this and we comply with Ofcom's decision in full. We will follow the directive as soon as the schedule and language are finalised."
