Bahrain Mirror (AFP): Iran has criticised as "unconstructive" a Bahraini court's decision to dissolve and seize the funds of the country's main Shiite opposition group.

The order came Sunday despite international criticism of the Gulf kingdom's intensified crackdown on dissent.

"Such actions by the Bahraini government prove that they don't seek to resolve the existing crises," said Iran's foreign ministry spokesman Bahram Ghasemi in a statement late Sunday.

Bahrain has unleashed a crackdown on opposition groups since a wave of pro-democracy protests in 2011 called for greater freedoms in the island nation.

Sunday's ruling came amid appeals by the United Nations, United States and rights groups for the legal action against Al-Wefaq to be dropped.

Ghasemi called on Bahrain to replace "escalated security and police approaches with trust-building measures," setting the stage for "serious, constructive and converging dialogue".

Authorities have stripped at least 261 people of their citizenship since 2012, according to the Bahrain Centre for Human Rights, including the country's Shiite spiritual leader Ayatollah, Sheikh Issa Qassem.

Dissolving "moderate groups" and stripping political and religious leaders of their citizenship are "not in line with the regime's interest," Ghasemi said.

Last month, Iran voiced concern over Bahrain's decision to strip Qassem of his nationality.

"Surely they know that the aggression against Ayatollah Sheikh Isa Qassem is a red line... that will leave no option for the people but to resort to armed resistance," said Qassem Suleimani, head of the elite Revolutionary Guards' overseas operations arm, the Quds Force.
