The British broadcaster was found to have committed a "major breach" of media regulations by not revealing that the narrator of a programme about the Gaza conflict was the son of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into 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 truthfulness".
The regulator has directed the corporation to air a evening statement about its decisions.
"Since this amounts to a significant violation of our rules, we are ordering the BBC to air a statement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be finalised," the statement read.
'Risk to Erode Trust'
The regulator's announcement declared: "Our investigation concluded that the documentary's failure to disclose that the voice's father served in a post in the Hamas-run government was materially misleading.
"This implied that the public did not have essential details which may have been very significant to their assessment of the presenter and the details he presented.
"Confidence is at the heart of the connection between a broadcaster and its public, notably for a state-funded media outlet such as the BBC.
"This error had the potential to damage the exceptionally strong levels of trust that viewers would have invested in a documentary produced by the BBC about the Gaza conflict."
The programme was withdrawn from the BBC's streaming service in February after the narrator's familial connections emerged, and in the month of July an corporation's own inquiry determined it breached the broadcaster's editorial guidelines on factual correctness.
A representative for the broadcaster commented: "The regulator's decision is in accordance with the conclusions of the internal assessment, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which corresponds to Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will adhere to the directive as soon as the timing and wording are finalised."
