Bahrain on Monday jailed five Shia on charges linked to "terrorism" and revoked their citizenships, the prosecution said.
Three defendants were found guilty of joining the clandestine "Al-Mukhtar Brigades" Shia group, possession of weapons for use in "terror" attacks and assaulting police, a prosecution statement said.
The criminal court sentenced each to 15 years in jail and stripped all three of their Bahraini citizenships, the statement said, adding that one of them is a fugitive on the run in Iraq.
The same court also jailed two alleged members of the outlawed Wafa Islamic Movement to 10 years and three years respectively after convicting them of taking part in a "terrorist" bombing carried out by the group, the prosecution said, adding that their nationalities were also revoked.
The verdicts were the latest in a series of rulings meted out against members of Bahrain's Shia by the authorities, who are also pushing court proceedings to dissolve the main opposition Al-Wefaq group.
Scores of Shia have been jailed over accusations of involvement in violence since a protest against the regime of the ruling Al-Khalifa Sunni dynasty was crushed in March 2011, a month after it erupted.
Protesters still frequently clash with police in Shia villages outside the capital, Manama.
Authorities have stripped at least 261 Bahrainis of their citizenship since 2012, according to the Bahrain Centre for Human Rights, including the Gulf state's Shia spiritual leader Sheikh Isa Qassem.
Activists have said that those losing their nationalities are usually given a one-year passport and a travel ticket to get to their destination.
