RNA - "Al-Khalifa must end systematic suppression against the oppressed and innocent people of Bahrain," Amir Abdollahian wrote on his Twitter page on Thursday.
He also deplored "collaboration between Bahraini security service" and the "illegitimate Israeli regime's Mossad" in a new wave of Bahrainis' crackdown as a move "against the regional collective security".
Earlier this month, people in the tiny Persian Gulf kingdom of Bahrain held anti-regime protests, expressing anger at crackdown on pro-democracy activists.
The demonstrations coincided with US Secretary of State Mike Pompe's visit to the kingdom as part of his tour of the Middle East.
The demonstrators in the villages of Diraz and al-Musalla honored those lost their lives during the anti-regime protests, and expressed their solidarity with the country's most prominent Shiite cleric, Sheikh Isa Qassim.
In June 2016, Bahraini authorities revoked Sheikh Qassim's citizenship over accusations that he used his position to serve foreign interests and promote violence, a charge the clergymen strongly denies.
According to Fars News Agancy, he has since been confined to house arrest, resulting in deterioration of his health condition.
In May 2017, a regime court convicted Sheikh Qassim of illegal collection of funds and money laundering, and sentenced him to one year in jail suspended for three years.
Last year, the cleric underwent surgeries in London. In December, he travelled to Iraq and is now believed to be there.
