The public service broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the presenter of a documentary about the Gaza conflict was the offspring of a Hamas representative, as ruled by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The BBC's director general had previously apologised, stating there had been "a major oversight in relation to accuracy".
Ofcom has ordered the corporation to broadcast a prime-time announcement about its decisions.
"As this represents a serious breach of our rules, we are ordering the corporation to air a message of our determinations against it on BBC Two at 9pm, with a schedule to be confirmed," the statement read.
'Risk to Undermine Trust'
The watchdog's report said: "Our investigation determined that the film's failure to disclose that the presenter's father held a role in the Hamas-administered government was significantly deceptive.
"It meant that the viewers did not have essential details which may have been very significant to their judgment of the voice and the details he shared.
"Trust is at the core of the bond between a media organization and its viewers, especially for a state-funded media outlet such as the public broadcaster.
"This failing had the risk to damage the significantly high levels of trust that viewers would have invested in a BBC factual programme about the Israel-Gaza war."
The film was withdrawn from the BBC's streaming service in last February after the presenter's personal associations emerged, and in July an internal BBC review concluded it breached the corporation's editorial guidelines on factual correctness.
A representative for the broadcaster said: "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 broadcaster's journalistic policies on factual correctness, which corresponds to regulation 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with Ofcom's decision in full. We will comply with the sanction as soon as the schedule and language are determined."
