The British broadcaster was found to have committed a "serious breach" of broadcasting rules by not revealing that the narrator of a documentary about the Gaza conflict was the child of a Hamas administrator, according to UK media regulator Ofcom.
An probe by the media regulator into Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The BBC's director general had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has directed the corporation to broadcast a prime-time announcement about its decisions.
"Given this constitutes a significant violation of our regulations, we are directing the corporation to transmit a statement of our findings against it on BBC Two at 21:00, with a timing to be confirmed," the statement read.
'Possibility to Undermine Credibility'
The watchdog's announcement declared: "The inquiry we conducted found that the programme's lack of disclosure that the voice's male guardian served in a position in the Hamas-administered government was substantially inaccurate.
"It meant that the viewers did not have vital facts which may have been very significant to their judgment of the presenter and the details he provided.
"Credibility is at the center of the bond between a television network and its public, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the possibility to damage the exceptionally strong levels of trust that the public would have placed in a BBC factual programme about the conflict in Gaza."
The documentary was removed from the online platform in 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 line with the results of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with the authority's determination in complete. We will comply with the directive as soon as the schedule and wording are confirmed."
