The BBC was found to have committed a "serious breach" of media regulations by failing to disclose that the voice of a documentary about the Gaza situation was the child of a Hamas official, as determined by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The chief executive of the broadcaster had previously apologised, stating there had been "a major oversight in relation to factual correctness".
The authority has ordered the corporation to air a evening announcement about its conclusions.
"As this represents a serious breach of our code, we are directing the broadcaster to broadcast a message of our findings against it on the BBC's second channel at 9pm, with a timing to be determined," the regulator stated.
'Possibility to Undermine Trust'
The authority's report stated: "Our probe found that the film's omission to reveal that the voice's father held a post in the Hamas-controlled government was substantially inaccurate.
"Consequently that the viewers did not have critical information which may have been highly relevant to their evaluation of the presenter and the content he presented.
"Trust is at the heart of the connection between a television network and its public, especially for a state-funded media outlet such as the public broadcaster.
"This error had the risk to damage the very considerable levels of trust that audiences would have placed in a BBC factual programme about the Gaza conflict."
The programme was removed from the online platform in the month of February after the boy's personal associations emerged, and in this past July an internal BBC review concluded it violated the broadcaster's journalistic standards on truthfulness.
A representative for the broadcaster commented: "The authority's determination is in accordance with the findings of the internal assessment, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in its entirety. We will adhere to the sanction as soon as the date and language are determined."
