The BBC engaged in a "serious breach" of media regulations by omitting to mention that the presenter of a programme about the Gaza conflict was the offspring of a Hamas official, as determined by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, noting there had been "a significant failing in relation to truthfulness".
Ofcom has ordered the BBC to transmit a prime-time statement about its findings.
"Given this constitutes a serious breach of our regulations, we are ordering the corporation to broadcast a message of our findings against it on BBC Two at 21:00, with a schedule to be finalised," the regulator stated.
'Possibility to Undermine Trust'
The watchdog's statement stated: "Our investigation found that the programme's lack of disclosure that the narrator's father served in a role in the Hamas-administered authority was materially misleading.
"This implied that the audience did not have vital facts which may have been highly relevant to their evaluation of the presenter and the information he provided.
"Confidence is at the core of the relationship between a television network and its public, notably for a national broadcasting corporation such as the public broadcaster.
"This oversight had the potential to erode the significantly high amounts of confidence that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The film was withdrawn from iPlayer in the month of February after the boy's personal associations emerged, and in the month of July an broadcaster's internal assessment concluded it violated the broadcaster's editorial guidelines on truthfulness.
A corporation official commented: "The authority's determination is in line with the conclusions of Peter Johnston's review, that there was a major oversight in the film in relation to the corporation's content standards on truthfulness, which aligns with clause 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the regulator's ruling in its entirety. We will adhere to the directive as soon as the timing and language are confirmed."
