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 son of a Hamas administrator, as ruled by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The BBC's director general had already issued an apology, saying there had been "a serious error in relation to truthfulness".
The authority has directed the BBC to transmit a evening statement about its decisions.
"Given this constitutes a serious breach of our regulations, we are instructing the corporation to air a statement of our findings against it on BBC2 at 9pm, with a timing to be finalised," the statement read.
'Risk to Undermine Credibility'
The authority's report declared: "Our probe found that the programme's omission to reveal that the voice's parent served in a position in the Hamas-controlled government was substantially inaccurate.
"It meant that the viewers did not have vital facts which may have been very significant to their evaluation of the presenter and the details he presented.
"Trust is at the core of the bond between a media organization and its audience, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the possibility to undermine the exceptionally strong degrees of confidence that audiences 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 the month of February after the presenter's family links emerged, and in the month of July an corporation's own inquiry found it infringed the broadcaster's editorial guidelines on truthfulness.
A corporation official said: "The regulator's decision is in agreement with the results of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on truthfulness, which reflects Rule 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the regulator's ruling in full. We will adhere to the penalty as soon as the schedule and language are confirmed."
