The BBC was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the voice of a programme about the Gaza situation was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The chief executive of the broadcaster had earlier expressed regret, noting there had been "a significant failing in relation to truthfulness".
The regulator has directed the corporation to broadcast a evening statement about its decisions.
"As this represents a significant violation of our rules, we are instructing the BBC to broadcast a statement of our findings against it on BBC2 at 9pm, with a timing to be finalised," it said.
'Possibility to Damage Trust'
The regulator's announcement stated: "Our investigation determined that the film's lack of disclosure that the presenter's male guardian occupied a post in the Hamas-controlled administration was materially misleading.
"This implied that the audience did not have essential details which may have been highly relevant to their judgment of the narrator and the information he presented.
"Trust is at the heart of the relationship between a broadcaster and its audience, especially for a public service broadcaster such as the BBC.
"This oversight had the possibility to erode the very considerable levels of trust that audiences would have placed in a BBC factual programme about the conflict in Gaza."
The programme was withdrawn from iPlayer in February after the narrator's familial connections emerged, and in this past July an corporation's own inquiry concluded it violated the broadcaster's content policies on accuracy.
A representative for the broadcaster commented: "The regulator's decision is in agreement with the results of the internal assessment, that there was a significant failing in the film in relation to the corporation's content standards on truthfulness, which aligns with Rule 2.2 of the regulator's media standards.
"We have apologised for this and we accept the authority's determination in its entirety. We will comply with the penalty as soon as the schedule and wording are determined."
