Bahrain Mirror - AFP: Bahrain began court proceedings to dissolve the main Shiite opposition bloc Al-Wefaq on Thursday, bringing the process forward in defiance of UN and US appeals for it to be dropped.

The bloc was the largest in parliament before its lawmakers resigned in protest at the crushing of 2011 protests calling for an elected government and Washington has labelled the crackdown on it "alarming".

The administrative court had not been due to meet on the government's request to dissolve Al-Wefaq until October 6 but brought the session forward at the request of Justice Minister Sheikh Khaled bin Ali Al-Khalifa, a judicial source said.

It set its next meeting for September 4.

But a statement by the ministry of justice said it will on Sunday request bringing the hearing forward, insisting the law of political association stipulates that a court decision in such a case should be reached "within a maximum of 30 days".

The court already suspended all of Al-Wefaq's activities on June 14, ordering its offices closed and assets frozen.

The justice ministry said the bloc provided a haven for "terrorism, radicalisation and violence" and opened the way for "foreign interference" in the kingdom's affairs.

That was an allusion to Iran, which Sunni-ruled Bahrain accuses of fomenting unrest among its Shiite majority.

Despite repeated appeals from its US ally for "reform and reconciliation", Bahrain has carried out an intensifying crackdown on leading Shiite figures.

On Monday, it stripped the kingdom's top Shiite cleric Sheikh Isa Qassim of his nationality, prompting street protests in his home village of Diraz, west of Manama.

The interior ministry said Thursday that police summoned a number of people who participated in the Diraz protests, adding that they will be referred to prosecution.

Last month, an appeals court more than doubled a four-year prison sentence handed down against Al-Wefaq leader Ali Salman on charges of inciting violence.

Amnesty International urged Bahraini authorities to halt its "intensified crackdown on the rights to freedom of expression, association and movement".

The London-based rights watchdog said it was "deeply concerned" by the decision to suspend Al-Wefaq.

Tiny but strategic Bahrain lies just across the Gulf from Iran and is the home base of the US Fifth Fleet.

It has been wracked by persistent unrest ever since the crushing of the 2011 protests.
