The BBC committed a "significant breach" of media regulations by failing to disclose that the presenter of a documentary about Gaza was the offspring of a Hamas representative, as determined by British broadcasting authority Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The BBC's director general had already issued an apology, noting there had been "a major oversight in relation to factual correctness".
The authority has directed the broadcaster to broadcast a peak-time announcement about its findings.
"As this represents a serious breach of our code, we are ordering the corporation to broadcast a announcement of our conclusions against it on BBC Two at nine o'clock in the evening, with a date to be confirmed," the statement read.
'Potential to Damage Trust'
The watchdog's report stated: "The inquiry we conducted found that the programme's omission to reveal that the voice's parent served in a role in the Hamas-run administration was materially misleading.
"Consequently that the audience did not have essential details which may have been extremely pertinent to their assessment of the presenter and the details he shared.
"Trust is at the center of the bond between a media organization and its public, especially for a public service broadcaster such as the BBC.
"This error had the risk to undermine the exceptionally strong amounts of trust that audiences would have invested in a factual film from the broadcaster about the Gaza conflict."
The film was pulled from the online platform in February after the boy's family links came to light, and in the month of July an internal BBC review determined it infringed the corporation's content policies on accuracy.
A corporation official commented: "The Ofcom ruling is in line with the conclusions of the internal assessment, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the regulator's ruling in full. We will adhere to the directive as soon as the timing and wording are confirmed."
