Police in Georgia have clashed with anti-government protesters trying to storm the presidential palace in the capital, Tbilisi.
According to the BBC, security forces used water cannons and pepper spray to disperse demonstrators.
The Caucasus country has been in crisis since the ruling Georgian Dream party claimed victory in last year's parliamentary election, which the pro-European Union opposition says was stolen. Since then, the government has paused talks on joining the EU.
The protest took place on the same day as local elections, which the opposition is largely boycotting following a government crackdown. One organiser had earlier called for leaders of the Georgian Dream party to be arrested.
Waving Georgian and EU flags, tens of thousands of protesters marched in central Tbilisi on Saturday.
One of the organisers, opera singer Paata Burchuladze, read out a declaration urging the employees of the Ministry of Internal Affairs to obey the will of the people and to immediately arrest six senior figures from the Georgian Dream party.
Demonstrators then marched on the presidential palace and tried to enter the compound, prompting riot police to fire pepper spray.
The demonstration follows a crackdown on activists, independent media and political opposition in recent months, with most of the leaders of the pro-Western opposition now behind bars.
Twenty-one-year-old Ia and her friends came to the Saturday rally prepared, dressed all in black, wearing helmets and gas masks.
"If we wear something colourful it will be easier to identify us, and if they identify us we are going to jail," she said, referring to the AI surveillance cameras installed on the main Rustaveli Avenue – the focal point for the ongoing protests.
Hundreds of protesters have been penalised with massive 5,000 Georgian lari ($1,835; £1,362) fines for what the authorities consider an illegal act of "blocking the streets".
"I want Georgian Dream to go. I want my country back. I want to be able to live peacefully and for my friends who are in jail, illegally imprisoned, to be free."
Ia sarcastically referred to the ruling party as "Russian Dream". This sentiment is shared by many of the anti-government protesters.
In the regions the Georgian Dream party enjoys support with its message that it can keep the peace, while in urban centres many Georgians believe their government is acting in Russia's interests.
The protest took place on the day of the municipal elections boycotted by most mainstream opposition parties, whose leaders are in jail.
