The public service broadcaster engaged in a "major breach" of media regulations by not revealing that the narrator of a film about Gaza was the offspring of a Hamas representative, as ruled by UK media regulator Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, noting there had been "a significant failing in relation to accuracy".
Ofcom has instructed the broadcaster to transmit a prime-time statement about its findings.
"Since this amounts to a significant violation of our code, we are directing the broadcaster to transmit a message of our conclusions against it on BBC Two at 21:00, with a timing to be confirmed," the regulator stated.
'Risk to Damage Credibility'
The regulator's announcement stated: "Our investigation concluded that the documentary's omission to reveal that the voice's male guardian held a role in the Hamas-administered administration was significantly deceptive.
"Consequently that the viewers did not have vital facts which may have been very significant to their assessment of the voice and the details he shared.
"Trust is at the core of the bond between a television network and its viewers, especially for a public service broadcaster such as the public broadcaster.
"This failing had the risk to erode the significantly high amounts of confidence that the public would have placed in a BBC factual programme about the Israel-Gaza war."
The programme was pulled from iPlayer in February after the boy's personal associations were revealed, and in July an internal BBC review found it breached the broadcaster's journalistic standards on truthfulness.
A BBC spokesperson commented: "The authority's determination is in accordance with the conclusions of Peter Johnston's review, that there was a serious error in the documentary in relation to the corporation's content standards on factual correctness, which reflects clause 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will adhere to the directive as soon as the date and wording are finalised."
