Amnesty says Iran's human rights record 'worsening'

A recent report by Amnesty International on Iran's human rights record suggests that authorities have been clamping down on freedom of expression in the run-up to parliamentary elections.

The 71-page report says that lawyers, students, journalists, political activists and human rights defenders have been arrested and imprisoned.

Iranian authorities refute these claims.
