LONDON — At least 304 people were killed in Iran during a three-day crackdown against protests across the country in November, according to a new Amnesty International toll published Monday.

The rights group had earlier estimated 208 deaths, including two youths aged 15 and 17.

Iran has dismissed such figures as "utter lies".

The nationwide demonstrations were triggered by a shock fuel price hike.

Authorities restored order within days, but so far have confirmed just five deaths, including four members of the security forces killed by "rioters".

An official death-toll based on figures from the national forensic institute is awaited.

With dozens held in "incommunicado detention" and others in "conditions amounting to enforced disappearance", some detention centres face "severe overcrowding", Amnesty claimed.

The organisation called on Tehran to "urgently and unconditionally release all those who have been arbitrarily detained". — AFP
