The British broadcaster was found to have committed a "major breach" of industry standards by omitting to mention that the narrator of a documentary about the Gaza conflict was the child of a Hamas official, as ruled by 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 "substantially inaccurate".
The head of the BBC had earlier expressed regret, noting there had been "a significant failing in relation to truthfulness".
The regulator has directed the broadcaster to transmit a peak-time announcement about its decisions.
"Since this amounts to a significant violation of our code, we are instructing the BBC to air a statement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be finalised," it said.
'Possibility to Damage Trust'
The regulator's report said: "Our investigation determined that the documentary's lack of disclosure that the narrator's parent occupied a role in the Hamas-run authority was significantly deceptive.
"It meant that the viewers did not have critical information which may have been extremely pertinent to their evaluation of the narrator and the details he presented.
"Trust is at the center of the connection between a broadcaster and its audience, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the possibility to undermine the very considerable levels of trust that viewers would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The programme was withdrawn from the BBC's streaming service in the month of February after the presenter's familial connections came to light, and in this past July an broadcaster's internal assessment concluded it breached the broadcaster's content policies on accuracy.
A BBC spokesperson stated: "The authority's determination is in accordance with the results of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the regulator's ruling in complete. We will comply with the directive as soon as the schedule and wording are finalised."
