Riot police in Georgia fired tear gas and water cannon to disperse crowds for a second night, as protests continued against a proposed law denounced by opponents as Russian-inspired.

A number of people were hurt during the protests after parliament approved the second reading of the controversial "foreign agent" bill on Wednesday.

The EU warns it could harm Tbilisi's ambitions of joining the bloc.

On Thursday, the US said the bill threatened free speech.

"The Georgian people want a European future for their country," Ursula von der Leyen posted on X. "Georgia is at a crossroads. It should stay the course on the road to Europe."

US National Security Council spokesman John Kirby said the White House was "deeply concerned" by the bill because of "what it could do in terms of stifling dissent and free speech".

The governing Georgian Dream party argues the bill will "boost transparency" of foreign funding, but protesters fear it could be used to crush critical voices ahead of parliamentary elections later this year.

Opponents say the measures are inspired by authoritarian legislation that neighbouring Russia uses to crush dissent.

Russia's 2012 law has since been used to marginalise voices challenging the Kremlin - including prominent cultural figures, media organisations and civil society groups.

The billionaire founder of Georgian Dream, Bidzina Ivanishvili, claimed this week that a Western "global war" party was using the country as part of its confrontation with Russia. He said Georgia had been set against Russia in 2008, when Russian forces invaded the country, again in 2014 when Russia seized Crimea from Ukraine, and then two years ago when Russia's full-scale war in Ukraine began.

The bill cleared its second reading with a vote of 83 to 23. After a third reading it has to be signed off by President Salome Zurabishvili, who has vowed to veto the bill, although Georgian Dream has sufficient numbers in parliament to overrule her.

Georgian Dream wants the law enacted by the end of the month. Once that happens, organisations would be required to state whether they are funded from abroad.

Georgia has been rocked by weeks of protests over the issue. On Tuesday night, clashes erupted between police and protesters on Rustaveli Avenue, outside parliament.

Several people were injured, including Levan Khabeishvili, chairman of the main opposition party United National Movement (UNM). He posted a picture of his bruised face on social media and later appeared in parliament, his face heavily bandaged.
