The British broadcaster was found to have committed a "significant breach" of broadcasting rules by omitting to mention that the narrator of a programme about the Gaza situation was the son of a Hamas representative, as ruled by regulatory body Ofcom.
An probe by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, noting there had been "a serious error in relation to factual correctness".
Ofcom has ordered the broadcaster to broadcast a evening statement about its findings.
"Given this constitutes a serious breach of our code, we are ordering the BBC to air a message of our findings against it on BBC Two at 9pm, with a schedule to be confirmed," the statement read.
'Potential to Damage Trust'
The authority's announcement said: "Our investigation determined that the documentary's lack of disclosure that the voice's male guardian occupied a position in the Hamas-run government was materially misleading.
"Consequently that the public did not have essential details which may have been very significant to their assessment of the presenter and the information he shared.
"Confidence is at the heart of the bond between a television network and its public, especially for a state-funded media outlet such as the British Broadcasting Corporation.
"This error had the possibility to undermine the significantly high degrees of credibility that viewers would have placed in a factual film from the broadcaster about the Gaza conflict."
The programme was pulled from the online platform in February after the narrator's familial connections came to light, and in July an corporation's own inquiry determined it violated the organization's editorial guidelines on accuracy.
A representative for the broadcaster said: "The Ofcom ruling is in accordance with the results of the internal assessment, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on accuracy, which corresponds to Rule 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the authority's determination in full. We will comply with the directive as soon as the schedule and language are confirmed."
