The public service broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the voice of a documentary about Gaza was the offspring of a Hamas official, as ruled by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The BBC's director general had already issued an apology, stating there had been "a significant failing in relation to truthfulness".
Ofcom has ordered the BBC to broadcast a prime-time declaration about its decisions.
"As this represents a serious breach of our rules, we are ordering the corporation to air a statement of our conclusions against it on the BBC's second channel at 9pm, with a timing to be confirmed," the regulator stated.
'Possibility to Damage Confidence'
The authority's statement said: "The inquiry we conducted concluded that the documentary's omission to reveal that the narrator's father occupied a post in the Hamas-administered authority was substantially inaccurate.
"This implied that the public did not have vital facts which may have been extremely pertinent to their assessment of the voice and the content he shared.
"Trust is at the core of the relationship between a media organization and its viewers, particularly for a national broadcasting corporation such as the BBC.
"This oversight had the risk to undermine the very considerable amounts of confidence that viewers would have invested in a factual film from the broadcaster about the Gaza conflict."
The documentary was pulled from the online platform in last February after the presenter's familial connections were revealed, and in this past July an corporation's own inquiry determined it infringed the corporation's journalistic standards on accuracy.
A BBC spokesperson commented: "The Ofcom ruling is in agreement with the conclusions of Peter Johnston's review, that there was a major oversight in the programme in relation to the corporation's content standards on factual correctness, which corresponds to regulation 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with the regulator's ruling in full. We will adhere to the directive as soon as the schedule and language are confirmed."
