The BBC was found to have committed a "major breach" of broadcasting rules by omitting to mention that the voice of a documentary about the Gaza situation was the son of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The chief executive of the broadcaster had already issued an apology, noting there had been "a major oversight in relation to factual correctness".
The authority has instructed the corporation to broadcast a evening declaration about its conclusions.
"Given this constitutes a significant violation of our rules, we are ordering the corporation to air a announcement of our determinations against it on BBC2 at 21:00, with a timing to be determined," the statement read.
'Potential to Damage Credibility'
The authority's announcement stated: "Our probe found that the film's failure to disclose that the presenter's parent served in a post in the Hamas-run authority was significantly deceptive.
"This implied that the audience did not have essential details which may have been highly relevant to their judgment of the voice and the information he shared.
"Trust is at the heart of the bond between a broadcaster and its public, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the risk to damage the very considerable amounts of credibility that the public would have invested in a documentary produced by the BBC about the Israel-Gaza war."
The programme was removed from the BBC's streaming service in the month of February after the narrator's family links were revealed, and in the month of July an broadcaster's internal assessment found it infringed the corporation's journalistic standards on factual correctness.
A BBC spokesperson commented: "The regulator's decision is in line with the results of Peter Johnston's review, that there was a major oversight in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which reflects Rule 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the regulator's ruling in its entirety. We will adhere to the sanction as soon as the timing and language are confirmed."
