The British broadcaster committed a "major breach" of industry standards by failing to disclose that the presenter of a film about the Gaza situation was the son of a Hamas official, as determined by British broadcasting authority Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The BBC's director general had already issued an apology, noting there had been "a serious error in relation to accuracy".
The authority has instructed the corporation to broadcast a evening statement about its conclusions.
"As this represents a serious breach of our rules, we are ordering the corporation to transmit a announcement of our conclusions against it on the BBC's second channel at 9pm, with a date to be confirmed," it said.
'Risk to Erode Credibility'
The authority's announcement stated: "Our investigation determined that the film's lack of disclosure that the voice's parent occupied a role in the Hamas-run government was substantially inaccurate.
"Consequently that the viewers did not have essential details which may have been very significant to their evaluation of the narrator and the content he shared.
"Trust is at the heart of the bond between a television network and its audience, especially for a state-funded media outlet such as the public broadcaster.
"This failing had the possibility to damage the exceptionally strong amounts of trust that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The film was pulled from the online platform in last February after the narrator's familial connections emerged, and in the month of July an corporation's own inquiry determined it infringed the corporation's journalistic standards on truthfulness.
A BBC spokesperson said: "The Ofcom ruling is in agreement with the results of the corporation's inquiry, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on accuracy, which reflects Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with Ofcom's decision in complete. We will adhere to the penalty as soon as the schedule and wording are finalised."
