The British broadcaster committed a "serious breach" of industry standards by omitting to mention that the narrator of a film about Gaza was the child of a Hamas official, as ruled by regulatory body Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The head of the BBC had already issued an apology, noting there had been "a serious error in relation to truthfulness".
The authority has ordered the broadcaster to air a evening statement about its conclusions.
"Given this constitutes a major infringement of our regulations, we are ordering the broadcaster to transmit a statement of our findings against it on BBC Two at 9pm, with a timing to be determined," it said.
'Possibility to Undermine Credibility'
The watchdog's report declared: "The inquiry we conducted determined that the film's failure to disclose that the presenter's father held a role in the Hamas-controlled government was significantly deceptive.
"Consequently that the public did not have vital facts which may have been very significant to their judgment of the presenter and the information he presented.
"Confidence is at the center of the bond between a broadcaster and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This failing had the possibility to damage the significantly high amounts of credibility that audiences would have invested in a BBC factual programme about the Gaza conflict."
The documentary was withdrawn from the BBC's streaming service in last February after the boy's personal associations came to light, and in the month of July an internal BBC review determined it breached the organization's editorial guidelines on factual correctness.
A corporation official stated: "The authority's determination is in agreement with the conclusions of Peter Johnston's review, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we agree with Ofcom's decision in full. We will comply with the directive as soon as the timing and wording are finalised."
