Lawmakers in Iran on Tuesday blamed the US and Israel for supporting the demonstrations which left one person killed and dozens injured a day before and urged the country's judiciary to issue death penalties to opposition leaders who incite civil unrest, Reuters reported.
"The main aim of Americans was to simulate the recent events in the Middle East in Iran to divert attentions from those countries," parliament speaker Ali Larijani told state radio.
"We have information...that America, Britain and Israel guided the opposition leaders who called for the rally," deputy police chief Ahmadreza Radan said, the semi-official Fars news agency reported.
In addition, judiciary spokesman Gholamhossein Mohseni-Ejei said that, "Those who created public disorder on Monday will be confronted firmly and immediately."
"[Opposition leaders] Mehdi Karroubi and Mirhossein Mousavi are corrupts on earth and should be tried," the official IRNA news agency quoted lawmakers as saying in a statement.
The charge "Corrupt on Earth" carries the death penalty in Iran.
Protests in Tehran and other surrounding cities appeared to have come to an end on Tuesday, according to Reuters.
