"The royal gesture, which marks the advent of Eid al-Adha, reflects the king's keenness on providing the pardoned prisoners the opportunity to integrate society anew and participate in their country's construction and development march," the official Bahrain News Agency reported Monday.
BNA did not provide further details about the pardons.
