The British broadcaster was found to have committed a "major breach" of industry standards by omitting to mention that the narrator of a programme about the Gaza conflict was the child of a Hamas administrator, according to regulatory body Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, noting there had been "a major oversight in relation to truthfulness".
Ofcom has instructed the broadcaster to broadcast a evening announcement about its decisions.
"Since this amounts to a significant violation of our rules, we are directing the broadcaster to transmit a message of our determinations against it on BBC2 at 21:00, with a date to be finalised," it said.
'Risk to Erode Confidence'
The watchdog's announcement stated: "Our probe concluded that the programme's lack of disclosure that the presenter's father held a position in the Hamas-administered administration was materially misleading.
"This implied that the public did not have vital facts which may have been extremely pertinent to their assessment of the presenter and the details he provided.
"Trust is at the heart of the connection between a broadcaster and its viewers, particularly for a state-funded media outlet such as the public broadcaster.
"This oversight had the potential to damage the exceptionally strong levels of confidence that the public would have invested in a documentary produced by the BBC about the Gaza conflict."
The programme was removed from the BBC's streaming service in last February after the boy's personal associations emerged, and in this past July an corporation's own inquiry determined it breached the broadcaster's editorial guidelines on accuracy.
A representative for the broadcaster said: "The regulator's decision is in line with the results of Peter Johnston's review, that there was a serious error in the programme in relation to the corporation's content standards on factual correctness, which reflects clause 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with Ofcom's decision in complete. We will comply with the directive as soon as the timing and wording are confirmed."
