The public service broadcaster committed a "serious breach" of media regulations by omitting to mention that the presenter of a film about the Gaza conflict was the child of a Hamas representative, as determined by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The head of the BBC had earlier expressed regret, stating there had been "a significant failing in relation to truthfulness".
Ofcom has instructed the broadcaster to transmit a peak-time statement about its findings.
"Since this amounts to a significant violation of our rules, we are ordering the broadcaster to air a statement of our findings against it on the BBC's second channel at nine o'clock in the evening, with a date to be determined," the statement read.
'Potential to Erode Trust'
The watchdog's statement stated: "Our investigation found that the film's omission to reveal that the presenter's father occupied a position in the Hamas-run administration was significantly deceptive.
"Consequently that the audience did not have essential details which may have been highly relevant to their evaluation of the voice and the information he provided.
"Trust is at the core of the relationship between a broadcaster and its audience, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the risk to erode the very considerable amounts of credibility that audiences would have put in a factual film from the broadcaster about the Gaza conflict."
The programme was withdrawn from the BBC's streaming service in last February after the presenter's familial connections were revealed, and in this past July an corporation's own inquiry concluded it violated the organization's editorial guidelines on factual correctness.
A representative for the broadcaster stated: "The regulator's decision is in agreement with the results of the corporation's inquiry, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in full. We will follow the directive as soon as the date and language are determined."
