The British broadcaster committed a "serious breach" of broadcasting rules by omitting to mention that the presenter of a film about the Gaza situation was the child of a Hamas representative, according to UK media regulator Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The BBC's director general had earlier expressed regret, stating there had been "a serious error in relation to truthfulness".
The regulator has instructed the corporation to air a prime-time declaration about its conclusions.
"Given this constitutes a major infringement of our regulations, we are directing the corporation to broadcast a statement of our conclusions against it on BBC2 at 21:00, with a schedule to be determined," it said.
'Risk to Damage Credibility'
The watchdog's announcement stated: "The inquiry we conducted determined that the film's failure to disclose that the voice's father served in a position in the Hamas-run government was materially misleading.
"This implied that the viewers did not have essential details which may have been extremely pertinent to their evaluation of the voice and the details he provided.
"Credibility is at the heart of the bond between a broadcaster and its public, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the potential to damage the significantly high levels of credibility that audiences would have put in a documentary produced by the BBC about the conflict in Gaza."
The documentary was withdrawn from the online platform in February after the narrator's familial connections came to light, and in July an corporation's own inquiry determined it violated the organization's journalistic standards on factual correctness.
A representative for the broadcaster commented: "The authority's determination is in agreement with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on factual correctness, which reflects regulation 2.2 of the regulator's media standards.
"We have apologised for this and we comply with Ofcom's decision in full. We will adhere to the sanction as soon as the schedule and wording are confirmed."
