Regime forces in Bahrain have handed a warrant to prominent cleric Sheikh Isa Qassim to appear in court, after clashing with his supporters.

Bahraini police forces used tear gas against Sheikh Qassim’s supporters around his residence in the western Diraz region of the country in a brutal effort to gain access to the doorway of the house on Wednesday.

The supporters of the cleric, who have been camping out at the area as a protective measure for his safety, called on more people from the local population to join them following the police raid.

The sit-in protest outside the cleric’s home entered its 185th day on Wednesday.

An image that appeared on social media shows Bahrainis around Sheikh Isa Qassim’s home as regime forces attack them on December 21, 2016.

The sit-in protest began on June 20, when Bahraini authorities stripped the 79-year-old cleric of his citizenship, less than a week after suspending the country’s main opposition party, the al-Wefaq National Islamic Society, and dissolving the Islamic Enlightenment Institution — founded by the senior cleric — and another opposition Islamic association.

Following the provocation against the cleric, a senior commander of Iran’s Islamic Revolution Guards Corps (IRGC) publicly declared that the sanctuary of the top cleric was a red line, the violation of which would set fire to Bahrain and the entire region.

Major General Qassem Soleimani, who commands the IRGC’s Quds Force, said in June that overstepping the red line would leave the people of Bahrain with no other choice but armed resistance.

Bahrain’s Interior Ministry had alleged in a statement that Sheikh Qassim actively sought the “creation of a sectarian environment” through his connections with “foreign powers,” charges that were widely understood as regime attempts to silence the dissident cleric. He has denied the charges.

Bahrain, a close ally of the US in the Persian Gulf region, has seen a wave of anti-regime protests since mid-February 2011. Scores of people have been killed and hundreds of others wounded or detained in a crackdown that Manama has been carrying out to crack down on dissent since then.

Soon, Saudi Arabia and the United Arab Emirates deployed forces to Bahrain to assist the Manama regime’s crackdown on the peaceful protests.

Human rights groups have frequently censured the Al Khalifah regime for rampant human rights abuses against the opposition and anti-regime demonstrators.

The regime has imprisoned other senior clerics in the past. Sheikh Ali Salman, one such figure, has been sentenced to nine years in jail in a sham trial.

Also on Wednesday, UK-based rights group Amnesty International (AI) issued a statement demanding that the Bahraini regime “halt its relentless crackdown on the rights to freedom of expression, association and peaceful assembly” across the country.

It further underlined that, over the past two months, regime forces had banned at least 40 human rights defenders and political activists in the country from traveling abroad while interrogating and filing charges against them.

Amnesty said it issued the statement after Bahraini authorities “notably intensified their clampdown on freedoms” across the Persian Gulf country since June 2016, when the regime announced its bid to strip away the citizenship of Sheikh Qassim.

The international rights group urged Bahraini officials to “release all prisoners of conscience” — including rights activist Nabeel Rajab and Sheikh Salman — “immediately and unconditionally.”
