The British broadcaster engaged in a "major breach" of broadcasting rules by omitting to mention that the voice of a documentary about the Gaza situation was the son of a Hamas administrator, according to UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The BBC's director general had previously apologised, saying there had been "a serious error in relation to truthfulness".
The regulator has instructed the broadcaster to air a evening statement about its findings.
"Given this constitutes a major infringement of our rules, we are directing the BBC to air a announcement of our determinations against it on BBC Two at 9pm, with a timing to be finalised," the statement read.
'Possibility to Erode Trust'
The watchdog's announcement said: "Our investigation concluded that the programme's omission to reveal that the narrator's parent occupied a position in the Hamas-controlled government was substantially inaccurate.
"It meant that the viewers did not have critical information which may have been extremely pertinent to their judgment of the narrator and the information he shared.
"Confidence is at the center of the relationship between a television network and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the possibility to damage the significantly high amounts of credibility that audiences would have put in a factual film from the broadcaster about the Gaza conflict."
The film was removed from the online platform in last February after the boy's familial connections were revealed, and in the month of July an corporation's own inquiry found it violated the broadcaster's journalistic standards on factual correctness.
A BBC spokesperson commented: "The regulator's decision is in agreement with the results of the internal assessment, that there was a significant failing in the film in relation to the corporation's content standards on truthfulness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept the authority's determination in full. We will adhere to the sanction as soon as the schedule and language are confirmed."
