The BBC was found to have committed a "significant breach" of industry standards by failing to disclose that the narrator of a documentary about the Gaza conflict was the offspring of a Hamas administrator, as determined by regulatory body Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has ordered the broadcaster to broadcast a evening statement about its decisions.
"Given this constitutes a serious breach of our code, we are instructing the corporation to air a message of our findings against it on BBC Two at 21:00, with a schedule to be determined," it said.
'Potential to Damage Trust'
The authority's announcement said: "Our investigation found that the documentary's omission to reveal that the narrator's male guardian served in a role in the Hamas-administered administration was materially misleading.
"This implied that the public did not have vital facts which may have been highly relevant to their judgment of the voice and the content he presented.
"Credibility is at the core of the bond between a media organization and its audience, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the risk to erode the significantly high amounts of confidence that audiences would have placed in a BBC factual programme about the Gaza conflict."
The film was removed from iPlayer in last February after the boy's familial connections came to light, and in the month of July an broadcaster's internal assessment concluded it infringed the organization's content policies on truthfulness.
A representative for the broadcaster commented: "The authority's determination is in agreement with the results of the internal assessment, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on truthfulness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with the authority's determination in full. We will adhere to the directive as soon as the schedule and wording are determined."
