The BBC was found to have committed a "serious breach" of industry standards by omitting to mention that the voice of a documentary about the Gaza conflict was the child of a Hamas official, according to UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The head of the BBC had earlier expressed regret, stating there had been "a significant failing in relation to factual correctness".
The regulator has directed the broadcaster to broadcast a prime-time statement about its findings.
"As this represents a significant violation of our code, we are directing the BBC to air a message of our determinations against it on BBC2 at 21:00, with a date to be determined," it said.
'Potential to Undermine Trust'
The watchdog's statement declared: "Our investigation determined that the programme's omission to reveal that the presenter's parent held a role in the Hamas-run administration was materially misleading.
"This implied that the viewers did not have critical information which may have been extremely pertinent to their assessment of the presenter and the content he provided.
"Trust is at the center of the connection between a television network and its public, especially for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to erode the very considerable degrees of credibility that the public would have invested in a documentary produced by the BBC about the conflict in Gaza."
The programme was removed from iPlayer in February after the narrator's personal associations were revealed, and in this past July an internal BBC review concluded it infringed the corporation's editorial guidelines on accuracy.
A BBC spokesperson commented: "The authority's determination is in agreement with the conclusions of the internal assessment, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to clause 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in full. We will comply with the sanction as soon as the timing and wording are confirmed."
