The BBC was found to have committed a "serious breach" of media regulations by failing to disclose that the narrator of a documentary about Gaza was the offspring of a Hamas administrator, as determined by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The BBC's director general had earlier expressed regret, stating there had been "a serious error in relation to factual correctness".
Ofcom has ordered the corporation to air a prime-time announcement about its decisions.
"Given this constitutes a significant violation of our rules, we are directing the corporation to air a announcement of our determinations against it on the BBC's second channel at 21:00, with a timing to be confirmed," the regulator stated.
'Potential to Erode Confidence'
The watchdog's statement stated: "Our investigation found that the film's lack of disclosure that the voice's parent served in a role in the Hamas-controlled authority was significantly deceptive.
"It meant that the viewers did not have essential details which may have been extremely pertinent to their judgment of the voice and the details he provided.
"Confidence is at the center of the relationship between a media organization and its viewers, notably for a public service broadcaster such as the public broadcaster.
"This oversight had the risk to erode the very considerable levels of confidence that audiences would have put in a factual film from the broadcaster about the conflict in Gaza."
The film was removed from the online platform in last February after the boy's family links came to light, and in this past July an broadcaster's internal assessment determined it infringed the organization's editorial guidelines on factual correctness.
A representative for the broadcaster said: "The authority's determination is in agreement with the findings of the corporation's inquiry, that there was a serious error in the documentary in relation to the corporation's content standards on truthfulness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept Ofcom's decision in complete. We will comply with the penalty as soon as the timing and language are determined."
