The British broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the narrator of a documentary about Gaza 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 film was "significantly deceptive".
The head of the BBC had earlier expressed regret, saying there had been "a serious error in relation to factual correctness".
The regulator has directed the corporation to air a evening statement about its conclusions.
"Since this amounts to a major infringement of our regulations, we are directing the BBC to broadcast a message of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be determined," the regulator stated.
'Possibility to Erode Trust'
The authority's report declared: "Our probe determined that the documentary's omission to reveal that the voice's parent occupied a position in the Hamas-administered authority was substantially inaccurate.
"This implied that the public did not have vital facts which may have been highly relevant to their judgment of the presenter and the information he provided.
"Confidence is at the center of the connection between a broadcaster and its public, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to erode the significantly high degrees of trust that the public would have put in a documentary produced by the BBC about the Israel-Gaza war."
The film was withdrawn from the online platform in the month of February after the boy's familial connections were revealed, and in the month of July an broadcaster's internal assessment concluded it violated the corporation's journalistic standards on accuracy.
A representative for the broadcaster stated: "The regulator's decision is in line with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the regulator's ruling in full. We will comply with the penalty as soon as the schedule and wording are determined."
