The BBC engaged in a "significant breach" of media regulations by not revealing that the presenter of a documentary about the Gaza situation was the son of a Hamas official, as determined by UK media regulator Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, saying there had been "a serious error in relation to truthfulness".
Ofcom has ordered the corporation to broadcast a evening declaration about its findings.
"Given this constitutes a serious breach of our code, we are instructing the broadcaster to air a statement of our findings against it on BBC2 at 9pm, with a timing to be confirmed," the statement read.
'Risk to Damage Credibility'
The watchdog's announcement said: "Our probe determined that the documentary's lack of disclosure that the narrator's father occupied a position in the Hamas-controlled authority was substantially inaccurate.
"Consequently that the public did not have essential details which may have been extremely pertinent to their evaluation of the voice and the details he provided.
"Trust is at the core of the bond between a media organization and its public, notably for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the potential to damage the exceptionally strong amounts of confidence that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The film was pulled from the BBC's streaming service in the month of February after the narrator's familial connections emerged, and in the month of July an broadcaster's internal assessment concluded it violated the broadcaster's content policies on factual correctness.
A BBC spokesperson stated: "The regulator's decision is in accordance with the results of the internal assessment, that there was a serious error in the programme in relation to the corporation's content standards on truthfulness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept Ofcom's decision in full. We will comply with the sanction as soon as the timing and language are finalised."
