The public service broadcaster was found to have committed a "major breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza conflict was the child of a Hamas representative, as ruled by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to accuracy".
Ofcom has ordered the BBC to broadcast a evening announcement about its decisions.
"Since this amounts to a significant violation of our regulations, we are ordering the corporation to air a message of our determinations against it on BBC Two at 21:00, with a date to be finalised," the regulator stated.
'Risk to Undermine Credibility'
The watchdog's report stated: "The inquiry we conducted determined that the film's omission to reveal that the presenter's father occupied a role in the Hamas-controlled administration was significantly deceptive.
"It meant that the viewers did not have vital facts which may have been very significant to their assessment of the voice and the information he shared.
"Credibility is at the core of the connection between a media organization and its public, particularly for a state-funded media outlet such as the public broadcaster.
"This oversight had the risk to undermine the exceptionally strong amounts of confidence that viewers would have placed in a factual film from the broadcaster about the Gaza conflict."
The documentary was pulled from iPlayer in the month of February after the presenter's family links came to light, and in this past July an internal BBC review determined it breached the broadcaster's content policies on accuracy.
A BBC spokesperson stated: "The Ofcom ruling is in agreement with the results of the corporation's inquiry, that there was a serious error in the programme in relation to the corporation's content standards on truthfulness, which corresponds to regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in its entirety. We will comply with the penalty as soon as the date and language are confirmed."
