The British broadcaster engaged in a "serious breach" of industry standards by omitting to mention that the presenter of a programme about the Gaza conflict was the offspring of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to factual correctness".
The regulator has directed the broadcaster to broadcast a evening statement about its conclusions.
"Given this constitutes a significant violation of our rules, we are directing the BBC to transmit a message of our findings against it on the BBC's second channel at nine o'clock in the evening, with a timing to be confirmed," the statement read.
'Risk to Erode Trust'
The regulator's report declared: "Our probe determined that the film's failure to disclose that the narrator's male guardian held a position in the Hamas-administered authority was substantially inaccurate.
"Consequently that the audience did not have essential details which may have been very significant to their evaluation of the voice and the information he shared.
"Trust is at the core of the connection between a broadcaster and its public, particularly for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to undermine the very considerable amounts of confidence that viewers would have invested in a BBC factual programme about the Israel-Gaza war."
The documentary was removed from iPlayer in the month of February after the narrator's family links were revealed, and in July an corporation's own inquiry determined it infringed the organization's editorial guidelines on factual correctness.
A representative for the broadcaster commented: "The Ofcom ruling is in line with the results of the corporation's inquiry, that there was a serious error in the film in relation to the corporation's content standards on factual correctness, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with the authority's determination in its entirety. We will follow the directive as soon as the schedule and wording are finalised."
