The public service broadcaster engaged in a "serious breach" of media regulations by not revealing that the narrator of a documentary about Gaza was the child of a Hamas representative, as ruled by regulatory body Ofcom.
An investigation by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The head of the BBC had earlier expressed regret, saying there had been "a major oversight in relation to factual correctness".
The authority has directed the broadcaster to air a evening statement about its findings.
"Since this amounts to a serious breach of our code, we are directing the broadcaster to air a statement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be finalised," the statement read.
'Risk to Undermine Confidence'
The authority's report declared: "The inquiry we conducted found that the programme's failure to disclose that the presenter's father held a position in the Hamas-run authority was substantially inaccurate.
"Consequently that the viewers did not have critical information which may have been highly relevant to their assessment of the narrator and the details he provided.
"Trust is at the core of the bond between a television network and its audience, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the very considerable degrees of trust that the public would have invested in a factual film from the broadcaster about the conflict in Gaza."
The programme was removed from iPlayer in the month of February after the boy's personal associations came to light, and in this past July an corporation's own inquiry determined it violated the corporation's journalistic standards on truthfulness.
A representative for the broadcaster commented: "The Ofcom ruling is in line with the results of the corporation's inquiry, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we accept the authority's determination in full. We will comply with the directive as soon as the timing and language are finalised."
