The BBC engaged in a "significant breach" of industry standards by omitting to mention that the presenter of a documentary about Gaza was the son of a Hamas official, according to UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The chief executive of the broadcaster had already issued an apology, saying there had been "a significant failing in relation to factual correctness".
Ofcom has instructed the corporation to air a evening declaration about its decisions.
"As this represents a major infringement of our regulations, we are ordering the corporation to air a announcement of our conclusions against it on BBC2 at 21:00, with a timing to be confirmed," it said.
'Possibility to Undermine Confidence'
The authority's announcement said: "Our probe concluded that the programme's omission to reveal that the voice's father served in a position in the Hamas-administered government was significantly deceptive.
"It meant that the viewers did not have vital facts which may have been highly relevant to their assessment of the voice and the content he presented.
"Confidence is at the center of the relationship between a television network and its viewers, notably for a public service broadcaster such as the public broadcaster.
"This oversight had the potential to undermine the significantly high degrees of credibility that audiences would have invested in a documentary produced by the BBC about the conflict in Gaza."
The film was pulled from the BBC's streaming service in last February after the narrator's personal associations came to light, and in the month of July an broadcaster's internal assessment determined it violated the organization's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The authority's determination is in line with the conclusions of Peter Johnston's review, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we accept Ofcom's decision in complete. We will follow the directive as soon as the date and wording are confirmed."
