The British broadcaster engaged in a "serious breach" of media regulations by failing to disclose that the presenter of a film about Gaza was the child of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The BBC's director general had previously apologised, saying there had been "a major oversight in relation to truthfulness".
The authority has directed the broadcaster to transmit a peak-time announcement about its decisions.
"As this represents a significant violation of our regulations, we are instructing the corporation to air a message of our findings against it on BBC2 at nine o'clock in the evening, with a date to be confirmed," the statement read.
'Possibility to Damage Trust'
The regulator's announcement declared: "The inquiry we conducted found that the documentary's omission to reveal that the narrator's father occupied a position in the Hamas-administered government was substantially inaccurate.
"It meant that the audience did not have critical information which may have been highly relevant to their assessment of the voice and the information he provided.
"Credibility is at the heart of the bond between a television network and its viewers, especially for a state-funded media outlet such as the BBC.
"This error had the risk to erode the exceptionally strong amounts of credibility that the public would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was removed from the online platform in the month of February after the presenter's personal associations emerged, and in this past July an corporation's own inquiry concluded it violated the broadcaster's journalistic standards on factual correctness.
A representative for the broadcaster stated: "The Ofcom ruling is in line with the findings of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to clause 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will follow the sanction as soon as the schedule and wording are confirmed."
