The public service broadcaster committed a "significant breach" of broadcasting rules by failing to disclose that the presenter of a film about Gaza was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a significant failing in relation to truthfulness".
The authority has instructed the corporation to transmit a prime-time announcement about its decisions.
"As this represents a serious breach of our code, we are ordering the corporation to transmit a statement of our conclusions against it on the BBC's second channel at 21:00, with a date to be determined," the regulator stated.
'Possibility to Damage Confidence'
The authority's statement declared: "Our investigation determined that the programme's failure to disclose that the presenter's parent occupied a post in the Hamas-run administration was significantly deceptive.
"It meant that the audience did not have vital facts which may have been very significant to their assessment of the narrator and the content he shared.
"Confidence is at the core of the relationship between a broadcaster and its viewers, particularly for a public service broadcaster such as the BBC.
"This oversight had the risk to erode the exceptionally strong amounts of trust that audiences would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was withdrawn from the BBC's streaming service in February after the boy's familial connections emerged, and in the month of July an internal BBC review found it infringed the organization's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The regulator's decision is in line with the conclusions of Peter Johnston's review, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the authority's determination in full. We will follow the sanction as soon as the schedule and wording are determined."
