The BBC engaged in a "major breach" of industry standards by not revealing that the voice of a programme about the Gaza situation was the son of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by the media regulator into Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to factual correctness".
The regulator has instructed the broadcaster to transmit a prime-time statement about its findings.
"Since this amounts to a significant violation of our regulations, we are directing the broadcaster to broadcast a statement of our findings against it on BBC Two at 21:00, with a date to be determined," the regulator stated.
'Potential to Undermine Credibility'
The authority's report stated: "The inquiry we conducted found that the programme's lack of disclosure that the voice's father occupied a role in the Hamas-controlled administration was significantly deceptive.
"It meant that the viewers did not have vital facts which may have been very significant to their evaluation of the voice and the information he shared.
"Trust is at the center of the bond between a media organization and its audience, particularly for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to undermine the very considerable degrees of confidence that the public would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The programme was removed from iPlayer in the month of February after the presenter's familial connections came to light, and in the month of July an internal BBC review concluded it violated the corporation's content policies on truthfulness.
A representative for the broadcaster commented: "The Ofcom ruling is in line with the findings of the corporation's inquiry, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on factual correctness, which aligns with Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept the authority's determination in complete. We will follow the directive as soon as the schedule and wording are finalised."
