The public service broadcaster committed a "serious breach" of media regulations by omitting to mention that the presenter of a film about the Gaza conflict was the offspring of a Hamas official, as determined by UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, stating there had been "a serious error in relation to accuracy".
The regulator has instructed the broadcaster to broadcast a evening statement about its conclusions.
"Since this amounts to a major infringement of our code, we are directing the broadcaster to broadcast a announcement of our findings against it on the BBC's second channel at nine o'clock in the evening, with a date to be determined," the statement read.
'Potential to Damage Credibility'
The regulator's announcement said: "Our investigation concluded that the film's lack of disclosure that the narrator's father held a post in the Hamas-controlled administration was significantly deceptive.
"It meant that the viewers did not have critical information which may have been highly relevant to their judgment of the narrator and the information he presented.
"Trust is at the heart of the connection between a media organization and its viewers, notably for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to undermine the significantly high levels of confidence that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The programme was removed from the BBC's streaming service in February after the boy's familial connections were revealed, and in the month of July an internal BBC review concluded it breached the corporation's editorial guidelines on factual correctness.
A corporation official stated: "The regulator's decision is in line with the findings of the internal assessment, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with the authority's determination in complete. We will adhere to the sanction as soon as the schedule and wording are determined."
