The British broadcaster engaged in a "significant breach" of media regulations by omitting to mention that the presenter of a film about the Gaza conflict was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to factual correctness".
The regulator has ordered the broadcaster to air a peak-time statement about its conclusions.
"As this represents a major infringement of our rules, we are directing the corporation to air a announcement of our findings against it on BBC2 at nine o'clock in the evening, with a timing to be finalised," the statement read.
'Possibility to Undermine Confidence'
The watchdog's statement stated: "Our investigation concluded that the programme's omission to reveal that the narrator's parent held a post in the Hamas-run administration was significantly deceptive.
"It meant that the audience did not have essential details which may have been highly relevant to their assessment of the voice and the details he presented.
"Trust is at the core of the connection between a media organization and its public, particularly for a national broadcasting corporation such as the BBC.
"This oversight had the potential to undermine the significantly high amounts of trust that audiences would have placed in a BBC factual programme about the Gaza conflict."
The documentary was withdrawn from the online platform in the month of February after the presenter's familial connections emerged, and in the month of July an corporation's own inquiry concluded it violated the corporation's content policies on truthfulness.
A corporation official stated: "The Ofcom ruling is in line with the findings of Peter Johnston's review, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which reflects regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the authority's determination in complete. We will adhere to the directive as soon as the date and wording are finalised."
