The British broadcaster was found to have committed a "major breach" of industry standards by not revealing that the presenter of a programme about Gaza was the offspring of a Hamas official, according to regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a major oversight in relation to truthfulness".
The authority has ordered the corporation to transmit a prime-time declaration about its decisions.
"As this represents a major infringement of our regulations, we are ordering the corporation to transmit a announcement of our determinations against it on BBC2 at 9pm, with a timing to be finalised," it said.
'Potential to Erode Trust'
The regulator's statement stated: "Our investigation concluded that the programme's lack of disclosure that the voice's male guardian held a role in the Hamas-administered authority was significantly deceptive.
"Consequently that the viewers did not have essential details which may have been highly relevant to their evaluation of the voice and the content he shared.
"Confidence is at the center of the bond between a broadcaster and its viewers, especially for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the very considerable amounts of confidence that audiences would have invested in a BBC factual programme about the Gaza conflict."
The programme was withdrawn from iPlayer in February after the boy's personal associations emerged, and in the month of July an broadcaster's internal assessment found it breached the organization's journalistic standards on accuracy.
A corporation official commented: "The regulator's decision is in accordance with the conclusions of the corporation's inquiry, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on accuracy, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in complete. We will comply with the directive as soon as the timing and wording are finalised."
