Georgian Prime Minister Irakli Kobakhidze on Tuesday agreed to hold talks with two former ministers and an opposition party on the country's European course, after days of increasingly tense protests by opposition supporters.

Irakli Kobakhidze warns opposition leaders and NGOs will be held accountable for mounting antigovernment protests.

Georgia, which has been criticized for using "excessive force" to crack down on anti-government protests, has become increasingly authoritarian, according to Western governments.

Georgia's rights ombudsman on Tuesday accused police of torturing pro-European Union protesters rallying for six consecutive days against the government's decision to shelve EU accession talks amid a post-election crisis.

Thousands of demonstrators gathered outside the parliament, throwing stones and setting off fireworks, while police deployed water cannons and tear gas.

Georgian Prime Minister Irakli Kobakhidze said on Tuesday that an attempt to stage what he called a "revolution" in the country had failed, after a fifth successive night of protests against a decision to suspend talks to join the European Union.

Police and protesters have clashed in Georgia after the country's ruling party suspended negotiations to join the European Union until 2028.

More than 200 people have been detained after four nights of protests in the Georgian capital over the government’s decision to suspend negotiations to join the European Union. The demonstrations came after the EU lambasted Georgia’s parliamentary elections.
