The public service broadcaster engaged in a "major breach" of media regulations by not revealing that the presenter of a film about Gaza was the son of a Hamas official, as ruled by UK media regulator Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The BBC's director general had previously apologised, stating there had been "a serious error in relation to accuracy".
The regulator has directed the corporation to broadcast a peak-time statement about its decisions.
"Since this amounts to a serious breach of our rules, we are ordering the corporation to broadcast a statement of our findings against it on BBC2 at 21:00, with a timing to be confirmed," it said.
'Possibility to Undermine Credibility'
The watchdog's report stated: "Our investigation concluded that the film's failure to disclose that the presenter's male guardian occupied a position in the Hamas-administered government was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been very significant to their evaluation of the narrator and the content he shared.
"Credibility is at the center of the connection between a broadcaster and its viewers, especially for a national broadcasting corporation such as the public broadcaster.
"This oversight had the risk to erode the very considerable degrees of confidence that the public would have put in a factual film from the broadcaster about the Gaza conflict."
The film was pulled from the online platform in last February after the presenter's personal associations were revealed, and in the month of July an internal BBC review found it breached the corporation's journalistic standards on factual correctness.
A BBC spokesperson commented: "The Ofcom ruling is in line with the results of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on accuracy, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in its entirety. We will adhere to the penalty as soon as the timing and language are confirmed."
