The public service broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the presenter of a film about Gaza was the offspring of a Hamas administrator, as ruled by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The BBC's director general had earlier expressed regret, stating there had been "a significant failing in relation to factual correctness".
The regulator has directed the corporation to air a peak-time announcement about its findings.
"As this represents a major infringement of our code, we are instructing the corporation to broadcast a announcement of our findings against it on BBC2 at 9pm, with a date to be confirmed," the regulator stated.
'Potential to Damage Credibility'
The regulator's statement stated: "Our probe determined that the documentary's lack of disclosure that the narrator's father held a post in the Hamas-run government was materially misleading.
"This implied that the public did not have critical information which may have been highly relevant to their judgment of the voice and the details he provided.
"Credibility is at the heart of the bond between a television network and its viewers, particularly for a public service broadcaster such as the BBC.
"This oversight had the potential to erode the significantly high levels of trust that viewers would have put in a factual film from the broadcaster about the Gaza conflict."
The documentary was withdrawn from iPlayer in the month of February after the presenter's personal associations emerged, and in this past July an internal BBC review found it breached the broadcaster's content policies on truthfulness.
A corporation official commented: "The regulator's decision is in line with the findings of the corporation's inquiry, that there was a serious error in the film in relation to the corporation's content standards on truthfulness, which aligns with regulation 2.2 of the regulator's media standards.
"We have apologised for this and we accept the authority's determination in complete. We will adhere to the directive as soon as the date and wording are confirmed."
