The BBC committed a "serious breach" of broadcasting rules by omitting to mention that the voice of a programme about the Gaza conflict was the child of a Hamas representative, according to UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The BBC's director general had already issued an apology, noting there had been "a serious error in relation to accuracy".
Ofcom has directed the BBC to transmit a evening declaration about its findings.
"Given this constitutes a serious breach of our code, we are instructing the broadcaster to transmit a message of our conclusions against it on the BBC's second channel at 9pm, with a timing to be finalised," it said.
'Potential to Damage Confidence'
The regulator's statement declared: "Our probe concluded that the documentary's omission to reveal that the narrator's parent served in a post in the Hamas-run administration was significantly deceptive.
"This implied that the viewers did not have essential details which may have been highly relevant to their judgment of the presenter and the information he provided.
"Trust is at the center of the connection between a media organization and its viewers, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This failing had the possibility to undermine the significantly high amounts of confidence that the public would have put in a BBC factual programme about the conflict in Gaza."
The programme was removed from the online platform in February after the boy's familial connections were revealed, and in this past July an corporation's own inquiry concluded it breached the organization's journalistic standards on accuracy.
A corporation official commented: "The authority's determination is in accordance with the conclusions of the internal assessment, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which reflects regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we comply with the authority's determination in full. We will adhere to the penalty as soon as the date and wording are determined."
