Bahrain’s High Criminal Court ruled on Wednesday that the accused had carried out a bombing attack against regime forces, possessed and produced explosives without license, and destroyed public properties, the al-Wasat daily reported.
The court also ordered the defendants to pay 250 Bahraini dinars (US 663 dollars) in indemnities.
They were arrested in the aftermath of a parcel bomb explosion in the village of Ma’ameer on August 14, 2015 even though no police officer was injured in the incident.
Thousands of anti-regime protesters have held demonstrations in Bahrain on an almost daily basis ever since a popular uprising began in the kingdom in mid-February 2011.
They are demanding that the Al Khalifah dynasty relinquish power and allow a just system representing all Bahrainis to be established.

Scores of people have lost their lives and hundreds of others sustained injuries or got arrested as a result of the Al Khalifah regime’s crackdown.
