The British broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the presenter of a film about the Gaza conflict was the offspring of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An inquiry by the media regulator into Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to truthfulness".
The regulator has instructed the broadcaster to air a prime-time statement about its conclusions.
"Given this constitutes a significant violation of our rules, we are ordering the corporation to transmit a message of our determinations against it on the BBC's second channel at 21:00, with a schedule to be confirmed," the statement read.
'Possibility to Undermine Credibility'
The watchdog's announcement stated: "The inquiry we conducted found that the film's failure to disclose that the presenter's parent held a post in the Hamas-controlled administration was significantly deceptive.
"It meant that the audience did not have essential details which may have been very significant to their assessment of the narrator and the details he shared.
"Trust is at the core of the connection between a media organization and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This error had the possibility to damage the significantly high levels of credibility that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The programme was pulled from the online platform in the month of February after the boy's family links emerged, and in July an corporation's own inquiry concluded it violated the broadcaster's content policies on truthfulness.
A corporation official commented: "The Ofcom ruling is in line with the conclusions of Peter Johnston's review, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the regulator's ruling in full. We will adhere to the directive as soon as the schedule and language are confirmed."
