The British broadcaster committed a "serious breach" of industry standards by failing to disclose that the presenter of a documentary about the Gaza situation was the child of a Hamas administrator, as determined by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The BBC's director general had already issued an apology, noting there had been "a serious error in relation to factual correctness".
Ofcom has instructed the broadcaster to air a peak-time declaration about its conclusions.
"Since this amounts to a serious breach of our code, we are instructing the broadcaster to air a announcement of our findings against it on BBC2 at 9pm, with a timing to be confirmed," the statement read.
'Possibility to Erode Credibility'
The regulator's report declared: "Our investigation found that the programme's failure to disclose that the narrator's father occupied a role in the Hamas-run administration was materially misleading.
"Consequently that the public did not have critical information which may have been extremely pertinent to their assessment of the narrator and the content he shared.
"Confidence is at the center of the relationship between a media organization and its viewers, especially for a public service broadcaster such as the BBC.
"This error had the risk to damage the significantly high degrees of confidence that viewers would have placed in a BBC factual programme about the Israel-Gaza war."
The documentary was pulled from iPlayer in last February after the presenter's family links were revealed, and in the month of July an corporation's own inquiry determined it violated the broadcaster's editorial guidelines on truthfulness.
A representative for the broadcaster stated: "The regulator's decision is in agreement with the results of the corporation's inquiry, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on accuracy, which aligns with Rule 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the regulator's ruling in full. We will adhere to the directive as soon as the schedule and language are determined."
