The BBC committed a "serious breach" of industry standards by not revealing that the presenter of a film about the Gaza conflict was the offspring of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to factual correctness".
Ofcom has directed the corporation to air a prime-time announcement about its decisions.
"As this represents a serious breach of our rules, we are ordering the broadcaster to transmit a statement of our conclusions against it on BBC Two at 21:00, with a timing to be determined," the regulator stated.
'Possibility to Erode Trust'
The regulator's report stated: "The inquiry we conducted concluded that the film's failure to disclose that the narrator's father served in a position in the Hamas-controlled government was significantly deceptive.
"This implied that the public did not have essential details which may have been highly relevant to their judgment of the narrator and the information he provided.
"Trust is at the center of the connection between a media organization and its viewers, notably for a public service broadcaster such as the BBC.
"This error had the potential to undermine the very considerable levels of credibility that viewers would have put in a BBC factual programme about the Israel-Gaza war."
The documentary was pulled from the online platform in February after the boy's familial connections were revealed, and in the month of July an broadcaster's internal assessment determined it violated the corporation's content policies on accuracy.
A corporation official stated: "The regulator's decision is in agreement with the results of Peter Johnston's review, that there was a significant failing in the documentary in relation to the BBC's Editorial Guidelines on factual correctness, which reflects clause 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with Ofcom's decision in complete. We will follow the directive as soon as the date and wording are finalised."
