The British broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the presenter of a film about the Gaza situation was the child of a Hamas representative, as ruled by UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, stating there had been "a major oversight in relation to truthfulness".
The regulator has ordered the BBC to transmit a prime-time declaration about its decisions.
"As this represents a significant violation of our code, we are directing the corporation to broadcast a announcement of our conclusions against it on BBC Two at 9pm, with a date to be determined," the regulator stated.
'Potential to Erode Confidence'
The watchdog's statement declared: "Our probe concluded that the documentary's failure to disclose that the narrator's father served in a post in the Hamas-controlled administration was significantly deceptive.
"Consequently that the public did not have critical information which may have been highly relevant to their evaluation of the narrator and the information he provided.
"Trust is at the center of the connection between a television network and its viewers, notably for a national broadcasting corporation such as the public broadcaster.
"This failing had the potential to erode the exceptionally strong amounts of trust that audiences would have put in a BBC factual programme about the Israel-Gaza war."
The programme was withdrawn from the BBC's streaming service in last February after the boy's personal associations emerged, and in the month of July an broadcaster's internal assessment concluded it breached the broadcaster's content policies on factual correctness.
A representative for the broadcaster commented: "The Ofcom ruling is in agreement with the findings of Peter Johnston's review, that there was a significant failing in the documentary in relation to the corporation's content standards on truthfulness, which corresponds to Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the authority's determination in complete. We will follow the penalty as soon as the date and wording are determined."
