The British broadcaster was found to have committed a "major breach" of broadcasting rules by not revealing that the narrator of a documentary about the Gaza situation was the son of a Hamas official, according to British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has directed the broadcaster to transmit a prime-time declaration about its decisions.
"Given this constitutes a major infringement of our regulations, we are instructing the BBC to transmit a statement of our conclusions against it on BBC2 at 21:00, with a schedule to be determined," the statement read.
'Risk to Damage Trust'
The authority's statement stated: "Our probe determined that the documentary's failure to disclose that the presenter's parent occupied a post in the Hamas-administered administration was materially misleading.
"It meant that the public did not have vital facts which may have been highly relevant to their evaluation of the voice and the details he presented.
"Confidence is at the core of the connection between a media organization and its public, particularly for a national broadcasting corporation such as the BBC.
"This oversight had the possibility to undermine the exceptionally strong degrees of confidence that audiences would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The film was withdrawn from iPlayer in February after the presenter's personal associations emerged, and in July an internal BBC review concluded it infringed the organization's journalistic standards on truthfulness.
A BBC spokesperson commented: "The Ofcom ruling is in line with the conclusions of the internal assessment, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept Ofcom's decision in its entirety. We will comply with the sanction as soon as the timing and language are confirmed."
