The British broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza conflict was the offspring of a Hamas official, as determined by regulatory body Ofcom.
An inquiry by the media regulator into Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The chief executive of the broadcaster had already issued an apology, saying there had been "a major oversight in relation to truthfulness".
The authority has directed the broadcaster to transmit a prime-time statement about its decisions.
"As this represents a serious breach of our regulations, we are instructing the broadcaster to air a message of our conclusions against it on BBC Two at 9pm, with a date to be finalised," the statement read.
'Potential to Erode Confidence'
The regulator's announcement declared: "Our investigation found that the film's omission to reveal that the voice's male guardian held a role in the Hamas-controlled government was substantially inaccurate.
"It meant that the viewers did not have vital facts which may have been highly relevant to their evaluation of the voice and the content he presented.
"Confidence is at the core of the connection between a television network and its public, especially for a state-funded media outlet such as the public broadcaster.
"This failing had the possibility to undermine the very considerable amounts of trust that audiences would have invested in a BBC factual programme about the Gaza conflict."
The film was removed from the online platform in February after the boy's family links emerged, and in July an corporation's own inquiry concluded it violated the organization's content policies on accuracy.
A corporation official commented: "The authority's determination is in line with the results of Peter Johnston's review, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on truthfulness, which reflects Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will follow the directive as soon as the timing and wording are determined."
