The British broadcaster committed a "serious breach" of broadcasting rules by omitting to mention that the presenter of a film about Gaza was the son of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The chief executive of the broadcaster had previously apologised, saying there had been "a major oversight in relation to truthfulness".
Ofcom has instructed the corporation to air a evening statement about its findings.
"Given this constitutes a major infringement of our code, we are directing the broadcaster to broadcast a announcement of our determinations against it on BBC Two at nine o'clock in the evening, with a date to be finalised," the regulator stated.
'Potential to Damage Trust'
The regulator's statement said: "The inquiry we conducted determined that the film's failure to disclose that the voice's parent occupied a position in the Hamas-run authority was significantly deceptive.
"It meant that the audience did not have vital facts which may have been very significant to their judgment of the presenter and the information he presented.
"Confidence is at the center of the relationship between a media organization and its public, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the possibility to damage the exceptionally strong degrees of credibility that audiences would have placed in a factual film from the broadcaster about the conflict in Gaza."
The documentary was removed from the BBC's streaming service in last February after the narrator's family links came to light, and in this past July an internal BBC review concluded it infringed the organization's editorial guidelines on factual correctness.
A representative for the broadcaster said: "The Ofcom ruling is in line with the findings of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept Ofcom's decision in complete. We will adhere to the directive as soon as the schedule and language are determined."
