At least 146 demonstrators were killed across Iran since leaders ordered security forces to stamp out protests that followed fuel price rises on November 15, Amnesty International said Monday.
"According to credible reports... those killed include at least 143 people," said the London-based rights group.
"The deaths have resulted almost entirely from the use of firearms."
"They must condemn these killings in the strongest possible terms and describe these events for what they are -- the deadly and wholly unwarranted use of force to crush dissent."
