The British broadcaster was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the voice of a film about the Gaza situation was the offspring of a Hamas administrator, according to British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, noting there had been "a significant failing in relation to factual correctness".
Ofcom has directed the broadcaster to air a prime-time declaration about its conclusions.
"As this represents a major infringement of our regulations, we are ordering the corporation to transmit a announcement of our findings against it on BBC Two at 21:00, with a timing to be confirmed," the statement read.
'Risk to Damage Trust'
The regulator's statement declared: "Our probe found that the documentary's omission to reveal that the voice's father held a position in the Hamas-administered administration was significantly deceptive.
"It meant that the viewers did not have vital facts which may have been extremely pertinent to their assessment of the presenter and the information he shared.
"Credibility is at the heart of the connection between a television network and its viewers, especially for a state-funded media outlet such as the BBC.
"This error had the possibility to damage the very considerable degrees of trust that audiences would have invested in a factual film from the broadcaster about the Gaza conflict."
The programme was removed from the online platform in February after the boy's personal associations emerged, and in the month of July an broadcaster's internal assessment concluded it infringed the corporation's content policies on accuracy.
A corporation official said: "The regulator's decision is in accordance with the results of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on accuracy, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we accept the regulator's ruling in full. We will follow the penalty as soon as the schedule and language are confirmed."
