The public service broadcaster engaged in a "serious breach" of industry standards by omitting to mention that the presenter of a programme about the Gaza situation was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a serious error in relation to truthfulness".
The regulator has directed the corporation to air a evening statement about its conclusions.
"Since this amounts to a significant violation of our code, we are ordering the broadcaster to air a announcement of our determinations against it on BBC Two at 21:00, with a timing to be finalised," it said.
'Risk to Damage Trust'
The regulator's announcement said: "The inquiry we conducted determined that the film's failure to disclose that the presenter's parent served in a position in the Hamas-administered authority was significantly deceptive.
"Consequently that the public did not have vital facts which may have been very significant to their assessment of the presenter and the content he provided.
"Credibility is at the heart of the relationship between a broadcaster and its public, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the possibility to damage the very considerable degrees of trust that audiences would have put in a BBC factual programme about the Gaza conflict."
The documentary was removed from the online platform in the month of February after the boy's family links were revealed, and in the month of July an corporation's own inquiry determined it infringed the organization's content policies on accuracy.
A corporation official commented: "The authority's determination is in agreement with the findings of the corporation's inquiry, that there was a major oversight in the documentary in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with the regulator's ruling in complete. We will follow the directive as soon as the timing and language are confirmed."
