The public service broadcaster engaged in a "serious breach" of industry standards by failing to disclose that the presenter of a documentary about Gaza was the child of a Hamas official, according to UK media regulator Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The head of the BBC had already issued an apology, saying there had been "a major oversight in relation to factual correctness".
The authority has instructed the BBC to transmit a evening announcement about its findings.
"Since this amounts to a serious breach of our regulations, we are instructing the BBC to air a announcement of our determinations against it on the BBC's second channel at 9pm, with a timing to be confirmed," the regulator stated.
'Potential to Undermine Credibility'
The authority's statement stated: "Our probe concluded that the documentary's omission to reveal that the voice's parent served in a position in the Hamas-controlled administration was materially misleading.
"It meant that the public did not have vital facts which may have been very significant to their evaluation of the presenter and the information he presented.
"Trust is at the heart of the relationship between a broadcaster and its public, notably for a public service broadcaster such as the BBC.
"This failing had the potential to erode the significantly high levels of confidence that audiences would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was pulled from the online platform in the month of February after the narrator's familial connections were revealed, and in this past July an broadcaster's internal assessment concluded it breached the organization's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The regulator's decision is in line with the results of Peter Johnston's review, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on accuracy, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with Ofcom's decision in full. We will follow the sanction as soon as the date and language are finalised."
