The British broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza conflict was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The head of the BBC had already issued an apology, saying there had been "a significant failing in relation to accuracy".
The authority has directed the BBC to transmit a prime-time statement about its findings.
"Since this amounts to a major infringement of our rules, we are instructing the corporation to broadcast a statement of our conclusions against it on the BBC's second channel at 9pm, with a schedule to be finalised," the statement read.
'Risk to Damage Credibility'
The authority's report declared: "The inquiry we conducted concluded that the documentary's failure to disclose that the narrator's father held a post in the Hamas-run government was materially misleading.
"Consequently that the viewers did not have essential details which may have been highly relevant to their judgment of the presenter and the details he provided.
"Trust is at the center of the relationship between a television network and its public, particularly for a national broadcasting corporation such as the BBC.
"This failing had the possibility to undermine the significantly high levels of trust that the public would have invested in a documentary produced by the BBC about the Gaza conflict."
The programme was removed from the online platform in last February after the presenter's personal associations came to light, and in the month of July an corporation's own inquiry found it violated the corporation's content policies on factual correctness.
A corporation official said: "The regulator's decision is in line with the findings of Peter Johnston's review, that there was a serious error in the film in relation to the corporation's content standards on factual correctness, which aligns with clause 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we agree with the regulator's ruling in complete. We will follow the sanction as soon as the schedule and wording are finalised."
