DUBAI, United Arab Emirates: A court in Bahrain on Sunday convicted the spiritual leader of the country's Shiite Muslims of collecting funds illegally and money laundering and sentenced him to one year in jail suspended for three years, local media reported.

The court also ordered Ayatollah Isa Qassim, who is in his mid-70s, to pay 100,000 Bahraini dinar ($265,266) in fines over the charges, which emanate from the collection of an Islamic tax called Khums, which in Shiite Islam is collected and spent by a senior cleric in the interests of the needy.

The case had ratcheted up tensions in the Western-allied Gulf Arab state where the U.S. Fifth Fleet is based.

The kingdom has been convulsed by occasional unrest since authorities crushed 2011 protests mainly by Shiites demanding a bigger share in running the country.

The Arabic-language al-Wasat said the court also ordered the confiscation of 3.367 million dinars found in a bank account in the cleric's name.

State news agency BNA, in a report that only referred to Qassim as a cleric, quoted the public prosecutor as saying the funds would be used for charity and humanitarian work once the ruling was deemed final.

"The public prosecutor asserted that the prosecution was currently studying the sentence to determine the possibility of an appeal," BNA said.

The trial is part of a wider crackdown on dissent that included a ban last year on the main Shiite Muslim group Wefaq. Authorities accuse it of fomenting sectarian unrest and having links to a foreign power, an apparent reference to Iran.

Bahrain's justice ministry took steps last week to dissolve the secular National Democratic Action Society (Waad) it accuses of supporting terrorism.

Qassim also faces expulsion from the kingdom after authorities revoked his citizenship last year for alleged foreign links and fomenting violence, charges he had denied.

His defense lawyers had refused to attend the hearings, which they saw as an attack on the country's Shiites.
