The BBC engaged in a "significant breach" of media regulations by omitting to mention that the presenter of a documentary about Gaza was the child of a Hamas representative, as ruled by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The BBC's director general had earlier expressed regret, noting there had been "a major oversight in relation to factual correctness".
Ofcom has ordered the corporation to air a peak-time statement about its conclusions.
"Given this constitutes a serious breach of our code, we are directing the broadcaster to broadcast a statement of our conclusions against it on BBC Two at 21:00, with a timing to be finalised," it said.
'Possibility to Erode Credibility'
The regulator's report declared: "Our investigation concluded that the documentary's lack of disclosure that the narrator's male guardian held a position in the Hamas-run authority was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been highly relevant to their evaluation of the presenter and the details he presented.
"Confidence is at the center of the bond between a broadcaster and its viewers, especially for a national broadcasting corporation such as the BBC.
"This error had the possibility to damage the very considerable degrees of confidence that audiences would have put in a BBC factual programme about the Israel-Gaza war."
The documentary was pulled from the online platform in last February after the boy's personal associations emerged, and in July an broadcaster's internal assessment determined it infringed the corporation's content policies on truthfulness.
A representative for the broadcaster stated: "The Ofcom ruling is in agreement with the results of the internal assessment, that there was a significant failing in the programme in relation to the corporation's content standards on factual correctness, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with Ofcom's decision in complete. We will follow the directive as soon as the schedule and wording are determined."
