The public service broadcaster engaged in a "serious breach" of industry standards by omitting to mention that the voice of a film about the Gaza situation was the son of a Hamas administrator, according to regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The BBC's director general had already issued an apology, saying there had been "a major oversight in relation to factual correctness".
Ofcom has ordered the BBC to air a evening statement about its conclusions.
"Given this constitutes a serious breach of our regulations, we are ordering the broadcaster to air a statement of our findings against it on BBC Two at 21:00, with a date to be confirmed," the statement read.
'Potential to Undermine Confidence'
The authority's statement stated: "Our probe determined that the programme's lack of disclosure that the voice's parent served in a position in the Hamas-controlled government was substantially inaccurate.
"It meant that the audience did not have critical information which may have been very significant to their assessment of the voice and the details he provided.
"Credibility is at the center of the bond between a media organization and its public, notably for a state-funded media outlet such as the public broadcaster.
"This oversight had the possibility to erode the exceptionally strong degrees of confidence that audiences would have put in a BBC factual programme about the Gaza conflict."
The documentary was removed from the online platform in February after the boy's personal associations came to light, and in the month of July an internal BBC review concluded it breached the broadcaster's content policies on accuracy.
A representative for the broadcaster commented: "The authority's determination is in line with the results of the internal assessment, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on accuracy, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the authority's determination in full. We will follow the directive as soon as the timing and language are confirmed."
