London Amnesty International has called for the release of Bahrain's 'prisoners of conscience'.
The call by the human rights organization comes on the anniversary of a protest movement that has led to two years of unrest and violence.
According to the BBC, more than two dozen activists are still in prison in Bahrain, including several sentenced to life imprisonment.
Amnesty said that 'it was time that people detained for exercising their right to freedom of expression be released'.
Amnesty International Middle East and North Africa Deputy Director Hassiba Hadj Sahraoui said that 'the government of Bahrain cannot carry on imprisoning people simply because it can't take criticism,' the report said.
He added that 'many of the allegations put forward by the prisoners of conscience have still not been investigated by the authorities,' it added.
Last month the group conducted a research trip to Bahrain where it met seven prisoners of conscience detained in Jaw prison in the capital, Manama. They included Nabeel Rajab, given a two-year sentence for encouraging 'illegal gatherings'.
No one from the Bahraini government was available to comment on Amnesty's charges, it added. Agencies
