The British broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the presenter of a programme about the Gaza situation was the son of a Hamas representative, as determined by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The head of the BBC had earlier expressed regret, noting there had been "a significant failing in relation to truthfulness".
Ofcom has instructed the BBC to air a prime-time statement about its findings.
"Since this amounts to a serious breach of our regulations, we are ordering the BBC to broadcast a announcement of our conclusions against it on BBC Two at 21:00, with a schedule to be finalised," the statement read.
'Possibility to Erode Trust'
The authority's announcement said: "The inquiry we conducted found that the programme's omission to reveal that the voice's father occupied a post in the Hamas-administered administration was significantly deceptive.
"Consequently that the audience did not have vital facts which may have been extremely pertinent to their evaluation of the presenter and the information he presented.
"Confidence is at the center of the connection between a media organization and its public, especially for a public service broadcaster such as the BBC.
"This oversight had the potential to undermine the significantly high degrees of confidence that audiences would have put in a factual film from the broadcaster about the Gaza conflict."
The programme was withdrawn from the online platform in last February after the presenter's personal associations came to light, and in July an broadcaster's internal assessment found it breached the broadcaster's editorial guidelines on factual correctness.
A corporation official stated: "The Ofcom ruling is in agreement with the results of the corporation's inquiry, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to regulation 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the regulator's ruling in complete. We will adhere to the sanction as soon as the timing and wording are finalised."
