The public service broadcaster committed a "serious breach" of broadcasting rules by failing to disclose that the presenter of a film about the Gaza conflict was the son of a Hamas official, as ruled by UK media regulator Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, saying there had been "a major oversight in relation to accuracy".
The authority has directed the broadcaster to transmit a evening statement about its decisions.
"Since this amounts to a major infringement of our regulations, we are directing the corporation to transmit a announcement of our findings against it on the BBC's second channel at 9pm, with a timing to be finalised," it said.
'Potential to Undermine Trust'
The authority's report stated: "Our investigation found that the film's omission to reveal that the presenter's male guardian occupied a position in the Hamas-administered authority was materially misleading.
"This implied that the viewers did not have vital facts which may have been very significant to their evaluation of the presenter and the information he presented.
"Confidence is at the heart of the connection between a broadcaster and its public, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the possibility to damage the significantly high degrees of credibility that the public would have placed in a documentary produced by the BBC about the conflict in Gaza."
The programme was removed from iPlayer in the month of February after the narrator's personal associations were revealed, and in this past July an corporation's own inquiry found it infringed the broadcaster's journalistic standards on truthfulness.
A corporation official commented: "The Ofcom ruling is in line with the findings of the internal assessment, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on accuracy, which aligns with regulation 2.2 of the regulator's media standards.
"We have apologised for this and we accept Ofcom's decision in complete. We will comply with the directive as soon as the schedule and wording are determined."
