The British broadcaster was found to have committed a "serious breach" of industry standards by not revealing that the narrator of a film about the Gaza conflict was the offspring of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, noting there had been "a serious error in relation to accuracy".
Ofcom has ordered the broadcaster to air a evening statement about its conclusions.
"As this represents a major infringement of our code, we are directing the BBC to transmit a message of our findings against it on BBC Two at 9pm, with a date to be finalised," it said.
'Risk to Undermine Trust'
The regulator's report said: "Our probe determined that the film's failure to disclose that the presenter's male guardian held a position in the Hamas-run administration was significantly deceptive.
"It meant that the audience did not have critical information which may have been very significant to their evaluation of the narrator and the information he shared.
"Confidence is at the core of the connection between a media organization and its audience, especially for a state-funded media outlet such as the public broadcaster.
"This failing had the possibility to erode the very considerable levels of trust that viewers would have invested in a factual film from the broadcaster about the conflict in Gaza."
The programme was pulled from iPlayer in the month of February after the narrator's family links emerged, and in the month of July an broadcaster's internal assessment determined it infringed the broadcaster's content policies on factual correctness.
A representative for the broadcaster stated: "The Ofcom ruling is in agreement with the conclusions of the internal assessment, that there was a major oversight in the film in relation to the corporation's content standards on truthfulness, which aligns with Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the regulator's ruling in complete. We will adhere to the penalty as soon as the date and wording are determined."
