The BBC was found to have committed a "major breach" of industry standards by omitting to mention that the presenter of a documentary about the Gaza conflict was the child of a Hamas representative, as ruled by UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to accuracy".
The regulator has directed the corporation to transmit a peak-time statement about its findings.
"Given this constitutes a major infringement of our regulations, we are directing the corporation to broadcast a announcement of our conclusions against it on the BBC's second channel at 21:00, with a schedule to be finalised," the statement read.
'Possibility to Erode Credibility'
The watchdog's announcement said: "Our probe found that the film's failure to disclose that the narrator's male guardian occupied a post in the Hamas-controlled administration was substantially inaccurate.
"This implied that the public did not have essential details which may have been highly relevant to their evaluation of the presenter and the content he presented.
"Trust is at the center of the connection between a television network and its viewers, especially for a national broadcasting corporation such as the public broadcaster.
"This failing had the risk to erode the exceptionally strong amounts of confidence that audiences would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The programme was withdrawn from the online platform in the month of February after the narrator's family links emerged, and in July an corporation's own inquiry concluded it infringed the broadcaster's content policies on accuracy.
A corporation official said: "The Ofcom ruling is in line with the conclusions of the internal assessment, that there was a significant failing in the film in relation to the corporation's content standards on accuracy, which reflects regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in full. We will adhere to the penalty as soon as the date and language are determined."
