The public service broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the presenter of a documentary about the Gaza conflict was the son of a Hamas official, according to regulatory body Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, saying there had been "a significant failing in relation to truthfulness".
The authority has ordered the broadcaster to air a evening statement about its decisions.
"Since this amounts to a serious breach of our code, we are instructing the BBC to air a announcement of our conclusions against it on BBC Two at 21:00, with a schedule to be confirmed," it said.
'Possibility to Undermine Confidence'
The regulator's statement stated: "Our investigation concluded that the documentary's failure to disclose that the voice's father occupied a position in the Hamas-controlled administration was substantially inaccurate.
"It meant that the audience did not have critical information which may have been highly relevant to their assessment of the presenter and the content he presented.
"Trust is at the center of the bond between a broadcaster and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the possibility to undermine the very considerable amounts of credibility that audiences would have put in a documentary produced by the BBC about the Israel-Gaza war."
The programme was withdrawn from iPlayer in the month of February after the presenter's personal associations were revealed, and in July an internal BBC review found it breached the broadcaster's content policies on factual correctness.
A representative for the broadcaster commented: "The regulator's decision is in line with the results of the corporation's inquiry, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we agree with the authority's determination in complete. We will comply with the directive as soon as the date and wording are determined."
