The public service broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the narrator of a programme about the Gaza situation was the son of a Hamas representative, as determined by UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, saying there had been "a significant failing in relation to accuracy".
Ofcom has ordered the corporation to air a evening statement about its findings.
"As this represents a serious breach of our rules, we are ordering the BBC to air a statement of our findings against it on BBC Two at 9pm, with a timing to be determined," the regulator stated.
'Risk to Damage Confidence'
The regulator's report said: "Our probe concluded that the programme's failure to disclose that the voice's male guardian served in a position in the Hamas-run authority was significantly deceptive.
"It meant that the public did not have vital facts which may have been very significant to their evaluation of the narrator and the details he provided.
"Trust is at the core of the relationship between a television network and its audience, particularly for a public service broadcaster such as the public broadcaster.
"This oversight had the risk to erode the significantly high amounts of trust that the public would have put in a documentary produced by the BBC about the Israel-Gaza war."
The programme was pulled from iPlayer in February after the boy's family links emerged, and in July an broadcaster's internal assessment found it violated the corporation's journalistic standards on accuracy.
A corporation official said: "The Ofcom ruling is in line with the results of the internal assessment, that there was a major oversight in the programme in relation to the corporation's content standards on truthfulness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we agree with the authority's determination in complete. We will adhere to the penalty as soon as the date and wording are finalised."
