The public service broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the voice of a programme about the Gaza situation was the offspring of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The BBC's director general had previously apologised, stating there had been "a serious error in relation to truthfulness".
The regulator has directed the broadcaster to transmit a evening declaration about its findings.
"As this represents a serious breach of our regulations, we are ordering the broadcaster to air a statement of our findings against it on BBC2 at 9pm, with a schedule to be finalised," the regulator stated.
'Potential to Undermine Credibility'
The regulator's announcement declared: "Our probe determined that the documentary's omission to reveal that the voice's parent occupied a position in the Hamas-administered government was materially misleading.
"This implied that the audience did not have vital facts which may have been extremely pertinent to their assessment of the presenter and the content he presented.
"Trust is at the center of the connection between a television network and its public, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This failing had the potential to undermine the very considerable amounts of trust that viewers would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was removed from the BBC's streaming service in the month of February after the presenter's familial connections emerged, and in the month of July an corporation's own inquiry concluded it breached the broadcaster's editorial guidelines on truthfulness.
A BBC spokesperson commented: "The Ofcom ruling is in line with the findings of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on truthfulness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept the authority's determination in full. We will comply with the sanction as soon as the date and language are determined."
