The public service broadcaster committed a "serious breach" of broadcasting rules by not revealing that the presenter of a documentary about Gaza was the child of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The head of the BBC had previously apologised, noting there had been "a major oversight in relation to truthfulness".
The authority has ordered the broadcaster to broadcast a evening statement about its decisions.
"As this represents a major infringement of our rules, we are ordering the corporation to air a statement of our conclusions against it on BBC2 at nine o'clock in the evening, with a timing to be determined," it said.
'Risk to Damage Credibility'
The regulator's report said: "Our investigation found that the programme's failure to disclose that the presenter's male guardian held a role in the Hamas-run administration was significantly deceptive.
"Consequently that the public did not have critical information which may have been very significant to their evaluation of the voice and the information he provided.
"Credibility is at the center of the bond between a media organization and its audience, notably for a state-funded media outlet such as the BBC.
"This failing had the possibility to undermine the exceptionally strong degrees of credibility that the public would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The film was pulled from iPlayer in the month of February after the presenter's personal associations emerged, and in July an corporation's own inquiry concluded it breached the broadcaster's journalistic standards on truthfulness.
A representative for the broadcaster said: "The regulator's decision is in agreement 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 truthfulness, which reflects regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in full. We will comply with the sanction as soon as the schedule and wording are finalised."
