Dubai: A court jailed three Bahraini activists on Thursday and stripped them of their nationality for planning an attack against the police in the kingdom, a judicial source said.

The men were jailed for ten years each for having planned an attack with explosives on policemen in August 2013, the source said.

Hundreds of activists have been arrested and faced trial in Bahrain since a month-long uprising calling for democratic reform was quelled in March 2011.

Bahrain last year adopted a law stipulating that suspects convicted of “terrorist” acts could be stripped of their nationality, a decision that has triggered condemnation by rights groups.

Dozens of activists have had their citizenship revoked since the law came into effect, and several have also been deported on charges of “undermining state security”.

The latest verdicts come as Bahrain prepares to hold elections on Saturday, with the opposition boycotting the polls.

The Shiite-led opposition is demanding a “real” constitutional monarchy with an elected prime minister who is independent from the ruling family.

The kingdom remains deeply divided nearly four years after authorities crushed the uprising.

Protests in villages around the capital still spark frequent clashes with police.
