The British broadcaster committed a "serious breach" of media regulations by failing to disclose that the presenter of a film about the Gaza conflict was the child of a Hamas official, as ruled by regulatory body Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The BBC's director general had previously apologised, saying there had been "a major oversight in relation to factual correctness".
Ofcom has directed the BBC to air a evening declaration about its findings.
"As this represents a serious breach of our regulations, we are instructing the BBC to air a message of our determinations against it on BBC2 at nine o'clock in the evening, with a timing to be finalised," the regulator stated.
'Possibility to Erode Credibility'
The watchdog's statement declared: "The inquiry we conducted concluded that the programme's omission to reveal that the presenter's parent held a role in the Hamas-run government was significantly deceptive.
"Consequently that the public did not have essential details which may have been highly relevant to their assessment of the narrator and the information he presented.
"Confidence is at the center of the bond between a broadcaster and its viewers, particularly for a public service broadcaster such as the BBC.
"This error had the potential to undermine the exceptionally strong amounts of confidence that viewers would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The programme was pulled from the BBC's streaming service in February after the presenter's family links were revealed, and in July an corporation's own inquiry found it violated the organization's journalistic standards on accuracy.
A BBC spokesperson commented: "The regulator's decision is in accordance with the findings of the internal assessment, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with the regulator's ruling in full. We will follow the directive as soon as the date and wording are determined."
