The British broadcaster was found to have committed a "significant breach" of industry standards by not revealing that the presenter of a film about Gaza was the offspring of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, saying there had been "a significant failing in relation to factual correctness".
Ofcom has directed the corporation to transmit a prime-time declaration about its conclusions.
"As this represents a major infringement of our rules, we are ordering the BBC to air a statement of our findings against it on BBC Two at nine o'clock in the evening, with a timing to be finalised," the regulator stated.
'Potential to Undermine Trust'
The watchdog's announcement said: "The inquiry we conducted concluded that the documentary's omission to reveal that the narrator's male guardian served in a post in the Hamas-controlled authority was significantly deceptive.
"It meant that the viewers did not have vital facts which may have been extremely pertinent to their assessment of the presenter and the content he provided.
"Trust is at the center of the bond between a television network and its public, particularly for a public service broadcaster such as the public broadcaster.
"This error had the risk to erode the significantly high amounts of credibility that the public would have put in a BBC factual programme about the Israel-Gaza war."
The film was withdrawn from iPlayer in the month of February after the narrator's personal associations came to light, and in this past July an internal BBC review concluded it breached the organization's content policies on accuracy.
A representative for the broadcaster stated: "The authority's determination is in accordance with the results of the corporation's inquiry, that there was a significant failing in the programme in relation to the corporation's content standards 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 comply with the directive as soon as the timing and wording are finalised."
