The British broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the narrator of a programme about Gaza was the child of a Hamas official, according to UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The BBC's director general had previously apologised, stating there had been "a major oversight in relation to factual correctness".
The authority has instructed the corporation to air a prime-time statement about its decisions.
"As this represents a significant violation of our code, we are ordering the broadcaster to transmit a statement of our findings against it on BBC2 at 9pm, with a timing to be confirmed," the regulator stated.
'Risk to Erode Confidence'
The watchdog's statement declared: "Our probe found that the documentary's failure to disclose that the presenter's father occupied a post in the Hamas-run administration was materially misleading.
"It meant that the public did not have essential details which may have been extremely pertinent to their assessment of the presenter and the content he presented.
"Credibility is at the center of the bond between a television network and its public, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the possibility to undermine the significantly high degrees of confidence that viewers would have put in a factual film from the broadcaster about the conflict in Gaza."
The programme was pulled from the online platform in February after the boy's familial connections came to light, and in July an internal BBC review determined it infringed the broadcaster's content policies on truthfulness.
A BBC spokesperson commented: "The authority's determination is in agreement with the conclusions of Peter Johnston's review, that there was a major oversight in the programme in relation to the corporation's content standards on factual correctness, which aligns with regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with the regulator's ruling in its entirety. We will adhere to the penalty as soon as the date and language are determined."
