A Bahraini man is on trial in the tiny Gulf kingdom for alleged ties to Iran.
Bahrain's state-run news agency says the defendant, Ibrahim Ghuloom Abdulwahab, is suspected of passing classified military information and sensitive economic data to Iran's Revolutionary Guard, a powerful armed wing of the Shiite theocracy.
Although Iran has no history of political ties to Bahrain's majority Shiites, the island's Sunni rulers accuse it of inciting dissent among their Shiite population.
Abdulwahab was due in court on Wednesday. Details of the proceedings have not been revealed, except for allegations that Abdulwahab has been the Guard's paid informant since 2002.
Media is banned from the trial. Bahrain imposed martial law last month to quell the Shiite-led protests.
