The BBC engaged in a "significant breach" of media regulations by failing to disclose that the presenter of a documentary about Gaza was the son of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to truthfulness".
The regulator has ordered the BBC to transmit a peak-time declaration about its conclusions.
"Given this constitutes a significant violation of our rules, we are ordering the corporation to transmit a message of our determinations against it on the BBC's second channel at 21:00, with a date to be determined," the statement read.
'Risk to Damage Confidence'
The regulator's report declared: "The inquiry we conducted determined that the programme's lack of disclosure that the voice's parent served in a post in the Hamas-administered authority was materially misleading.
"This implied that the audience did not have essential details which may have been highly relevant to their judgment of the narrator and the details he presented.
"Trust is at the core of the bond between a television network and its public, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the possibility to erode the very considerable degrees of credibility that viewers would have placed in a documentary produced by the BBC about the conflict in Gaza."
The documentary was pulled from iPlayer in last February after the presenter's familial connections came to light, and in this past July an corporation's own inquiry concluded it infringed the corporation's content policies on truthfulness.
A BBC spokesperson said: "The Ofcom ruling is in agreement with the results of the corporation's inquiry, that there was a major oversight in the programme in relation to the corporation's content standards on factual correctness, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept Ofcom's decision in complete. We will adhere to the sanction as soon as the date and wording are finalised."
