The public service broadcaster was found to have committed a "major breach" of media regulations by failing to disclose that the presenter of a programme about Gaza was the son of a Hamas administrator, according to British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The head of the BBC had previously apologised, saying there had been "a serious error in relation to factual correctness".
The authority has directed the BBC to transmit a prime-time statement about its findings.
"Given this constitutes a major infringement of our regulations, we are instructing the corporation to broadcast a announcement of our findings against it on BBC Two at 21:00, with a timing to be finalised," the statement read.
'Potential to Undermine Confidence'
The regulator's report declared: "Our probe concluded that the film's lack of disclosure that the voice's parent served in a role in the Hamas-controlled administration was significantly deceptive.
"It meant that the viewers did not have vital facts which may have been extremely pertinent to their evaluation of the narrator and the details he shared.
"Trust is at the core of the connection between a television network and its viewers, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to undermine the significantly high amounts of credibility that the public would have invested in a factual film from the broadcaster about the conflict in Gaza."
The programme was removed from the online platform in last February after the narrator's family links emerged, and in the month of July an broadcaster's internal assessment concluded it infringed the organization's content policies on factual correctness.
A corporation official commented: "The authority's determination is in line with the results of Peter Johnston's review, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we comply with the authority's determination in its entirety. We will comply with the directive as soon as the schedule and language are determined."
