The public service broadcaster was found to have committed a "serious breach" of media regulations by omitting to mention that the presenter of a film about the Gaza conflict was the son of a Hamas administrator, as determined by regulatory body Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the documentary was "substantially inaccurate".
The head of the BBC had earlier expressed regret, stating there had been "a serious error in relation to factual correctness".
The regulator has directed the corporation to broadcast a evening statement about its findings.
"As this represents a significant violation of our rules, we are instructing the broadcaster to transmit a announcement of our determinations against it on the BBC's second channel at 9pm, with a date to be finalised," it said.
'Possibility to Erode Confidence'
The authority's statement declared: "Our investigation determined that the programme's lack of disclosure that the voice's father held a role in the Hamas-administered administration was significantly deceptive.
"Consequently that the public did not have vital facts which may have been extremely pertinent to their assessment of the narrator and the content he provided.
"Trust is at the heart of the connection between a television network and its audience, especially for a state-funded media outlet such as the BBC.
"This failing had the potential to damage the very considerable levels of credibility that viewers would have invested in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was withdrawn from the BBC's streaming service in last February after the boy's personal associations came to light, and in the month of July an corporation's own inquiry found it infringed the corporation's editorial guidelines on accuracy.
A corporation official stated: "The authority's determination is in line with the conclusions of the internal assessment, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on accuracy, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept the authority's determination in complete. We will comply with the directive as soon as the date and wording are finalised."
