DUBAI - Bahrain's top criminal court on Monday sentenced four Shiite Muslims to death for a 2017 bombing that killed a policeman, a judicial official and the public prosecutor said.
A statement by the prosecutor's office said the four were found guilty on charges of premeditated murder and possession of unlicensed arms "with terrorist aims" over a June 18, 2017 bombing.
A police officer was killed in the blast in Diraz, a flashpoint village outside the capital Manama.
Bahrain, a tiny Sunni-ruled kingdom located between regional rivals Saudi Arabia and Iran, has been hit by waves of unrest since 2011, when security forces crushed protests led by majority Shiites demanding an elected prime minister.
Authorities have since jailed hundreds of dissidents and stripped many of citizenship, banning all opposition groups under court orders.
Diraz in particular has been rocked by protests, police raids, riots and sporadic bombings.
The village is home to Sheikh Isa Qassim, Bahrain's highest Shiite dignitary, who was stripped of citizenship in 2016 and is under house arrest.
Bahraini authorities accuse Shiite Iran of provoking unrest in the kingdom, which Iran denies.
Monday's verdict comes ahead of controversial parliamentary elections that Bahrain's King Hamad has called for November 24.
Dissolved opposition parties, including the Shiite Al-Wefaq and secular Al-Waad, do not have the right to put forward their own candidates in the vote.
Bahrain, a key ally of the United States, is home to the US Fifth Fleet and a permanent British military base.
