The public service broadcaster committed a "serious breach" of media regulations by not revealing that the presenter of a film about the Gaza situation was the offspring of a Hamas official, as determined by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the programme was "materially misleading".
The chief executive of the broadcaster had previously apologised, noting there had been "a serious error in relation to factual correctness".
Ofcom has directed the BBC to broadcast a peak-time announcement about its conclusions.
"Since this amounts to a serious breach of our regulations, we are directing the broadcaster to air a announcement of our findings against it on BBC2 at nine o'clock in the evening, with a date to be finalised," the statement read.
'Possibility to Undermine Credibility'
The watchdog's report stated: "Our investigation found that the film's lack of disclosure that the presenter's parent occupied a position in the Hamas-controlled authority was significantly deceptive.
"Consequently that the public did not have essential details which may have been extremely pertinent to their evaluation of the presenter and the information he shared.
"Confidence is at the center of the relationship between a broadcaster and its viewers, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This failing had the possibility to damage the significantly high levels of confidence that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was pulled from the online platform in last February after the boy's familial connections came to light, and in July an broadcaster's internal assessment determined it infringed the organization's content policies on truthfulness.
A corporation official said: "The Ofcom ruling is in agreement with the results of Peter Johnston's review, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with clause 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the authority's determination in its entirety. We will follow the directive as soon as the date and language are confirmed."
