The public service broadcaster committed a "major breach" of industry standards by failing to disclose that the presenter of a programme about Gaza was the offspring of a Hamas official, as ruled by UK media regulator Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The BBC's director general had previously apologised, saying there had been "a serious error in relation to accuracy".
Ofcom has directed the corporation to broadcast a prime-time statement about its decisions.
"As this represents a significant violation of our regulations, we are ordering the BBC to air a announcement of our conclusions against it on BBC2 at nine o'clock in the evening, with a date to be confirmed," the statement read.
'Risk to Undermine Confidence'
The authority's report stated: "Our investigation found that the programme's omission to reveal that the presenter's parent held a position in the Hamas-controlled authority was substantially inaccurate.
"This implied that the audience did not have critical information which may have been highly relevant to their assessment of the narrator and the details he presented.
"Trust is at the center of the relationship between a television network and its viewers, particularly for a public service broadcaster such as the BBC.
"This failing had the risk to undermine the very considerable degrees of trust that viewers would have invested in a factual film from the broadcaster about the Gaza conflict."
The film was removed from the BBC's streaming service in the month of February after the presenter's familial connections came to light, and in this past July an corporation's own inquiry found it breached the broadcaster's journalistic standards on truthfulness.
A representative for the broadcaster commented: "The Ofcom ruling is in line with the conclusions of the corporation's inquiry, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with Ofcom's decision in full. We will comply with the directive as soon as the date and language are determined."
