The British broadcaster committed a "major breach" of broadcasting rules by not revealing that the presenter of a documentary about the Gaza situation was the son of a Hamas official, as determined by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a serious error in relation to factual correctness".
The authority has directed the broadcaster to broadcast a evening declaration about its findings.
"Since this amounts to a significant violation of our rules, we are ordering the corporation to air a statement of our findings against it on BBC Two at 21:00, with a schedule to be finalised," the statement read.
'Possibility to Erode Trust'
The regulator's statement declared: "Our investigation determined that the programme's omission to reveal that the presenter's father held a role in the Hamas-controlled government was significantly deceptive.
"It meant that the public did not have critical information which may have been very significant to their judgment of the voice and the details he provided.
"Confidence is at the core of the bond between a media organization and its public, particularly for a national broadcasting corporation such as the BBC.
"This oversight had the potential to erode the significantly high amounts of credibility that the public would have placed in a BBC factual programme about the Israel-Gaza war."
The film was pulled from the BBC's streaming service in the month of February after the boy's family links came to light, and in the month of July an broadcaster's internal assessment concluded it violated the corporation's editorial guidelines on truthfulness.
A corporation official stated: "The authority's determination is in accordance with the conclusions of Peter Johnston's review, that there was a serious error in the documentary in relation to the corporation's content standards on factual correctness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we agree with the regulator's ruling in complete. We will adhere to the sanction as soon as the timing and language are confirmed."
