The British broadcaster was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza conflict was the son of a Hamas official, as determined by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The chief executive of the broadcaster had earlier expressed regret, noting there had been "a serious error in relation to factual correctness".
The authority has directed the broadcaster to transmit a prime-time statement about its decisions.
"As this represents a major infringement of our rules, we are ordering the corporation to transmit a announcement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be finalised," it said.
'Potential to Damage Confidence'
The regulator's report stated: "Our investigation determined that the film's omission to reveal that the presenter's male guardian held a role in the Hamas-controlled administration was materially misleading.
"It meant that the audience did not have vital facts which may have been highly relevant to their assessment of the narrator and the information he presented.
"Trust is at the center of the bond between a television network and its public, especially for a public service broadcaster such as the public broadcaster.
"This error had the potential to damage the significantly high amounts of trust that viewers would have put in a BBC factual programme about the Israel-Gaza war."
The documentary was withdrawn from the BBC's streaming service in the month of February after the narrator's family links were revealed, and in the month of July an broadcaster's internal assessment concluded it violated the corporation's content policies on accuracy.
A corporation official said: "The Ofcom ruling is in accordance with the conclusions of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with the authority's determination in complete. We will adhere to the directive as soon as the timing and language are confirmed."
