While thousands are taking to the streets in Iran today to mark the 31st anniversary of the revolution, the Iranian opposition movement is planning to hijack official celebrations despite threats of a widespread crackdown.

Amnesty International has condemned the “wholly avoidable” deaths of up to 15 people in Iran during the recent Ashoura religious commemorations. The Iranian government has also been criticised for its treatment of protesters.

Human rights groups have protested to the Iran over a longstanding travel ban on a journalist and activist which has prevented him from receiving the Martin Ennals Award in person.

The Iranian authorities must immediately release dozens of people arrested last week during a prayer service in support of activists detained following protests after June’s presidential election, Amnesty International has said.
