The British broadcaster was found to have committed a "significant breach" of industry standards by failing to disclose that the narrator of a film about the Gaza conflict was the child of a Hamas official, according to UK media regulator Ofcom.
An probe by the broadcasting watchdog into Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The BBC's director general had earlier expressed regret, stating there had been "a serious error in relation to accuracy".
The regulator has ordered the BBC to broadcast a peak-time statement about its findings.
"As this represents a serious breach of our code, we are ordering the corporation to broadcast a message of our findings against it on the BBC's second channel at nine o'clock in the evening, with a timing to be determined," the regulator stated.
'Risk to Undermine Credibility'
The regulator's statement said: "Our investigation determined that the programme's lack of disclosure that the presenter's father served in a position in the Hamas-administered administration was significantly deceptive.
"This implied that the viewers did not have essential details which may have been very significant to their assessment of the narrator and the details he provided.
"Credibility is at the center of the bond between a broadcaster and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the risk to undermine the exceptionally strong amounts of credibility that audiences would have put in a factual film from the broadcaster about the conflict in Gaza."
The documentary was withdrawn from the BBC's streaming service in the month of February after the boy's familial connections emerged, and in this past July an internal BBC review concluded it breached the corporation's content policies on factual correctness.
A representative for the broadcaster commented: "The regulator's decision is in agreement with the conclusions of Peter Johnston's review, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on factual correctness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the regulator's ruling in its entirety. We will adhere to the directive as soon as the schedule and language are determined."
