The public service broadcaster was found to have committed a "major breach" of industry standards by not revealing that the presenter of a film about the Gaza conflict was the offspring of a Hamas official, according to regulatory body Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The BBC's director general had earlier expressed regret, noting there had been "a major oversight in relation to truthfulness".
The authority has directed the BBC to transmit a prime-time statement about its decisions.
"As this represents a significant violation of our rules, we are instructing the broadcaster to transmit a message of our determinations against it on BBC2 at nine o'clock in the evening, with a timing to be finalised," the regulator stated.
'Potential to Damage Credibility'
The authority's statement stated: "Our investigation determined that the programme's failure to disclose that the narrator's father served in a position in the Hamas-controlled government was significantly deceptive.
"This implied that the public did not have essential details which may have been extremely pertinent to their assessment of the presenter and the information he provided.
"Trust is at the core of the connection between a media organization and its viewers, particularly for a national broadcasting corporation such as the BBC.
"This failing had the possibility to erode the significantly high amounts of confidence that the public would have put in a documentary produced by the BBC about the conflict in Gaza."
The film was pulled from iPlayer in February after the boy's family links were revealed, and in this past July an corporation's own inquiry determined it infringed the organization's content policies on truthfulness.
A corporation official stated: "The Ofcom ruling is in accordance with the results of the internal assessment, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to clause 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will comply with the penalty as soon as the date and language are determined."
