Protests in France turned violent over the weekend.

Demonstrators smashed shop windows, burned barricades and torched vehicles as they clashed with riot police in Paris.

The riots were the second consecutive weekend of unrest in France after the proposal of a draft security law. Protests against the security law and police brutality began last week after President Emmanuel Macron announced new restrictive measures.  

Critics said its passing was a violation of civil liberties. Anger against the government intensified late November after a video of a black man being beaten by several police officers spread online.

Paris demonstrations started peacefully, with thousands of people joining the call for the government to scrap the new law. However, clashes between members of the "Black Bloc" group and riot police erupted not long after.

Rallies were also held in Marseille, Lille and Lyon. None of these turned violent.

One group was reported to have ransacked a Paris bank and burned documents outside the branch. Police used tear gas and other weapons while protesters lobbed projectiles.

Paris police said that at least 500 "hoodlums" had infiltrated the peaceful protest and turned it violent. Police said they arrested at least 30.

The security bill, introduced in parliament last week, intends to increase the country's surveillance and bar the circulation of images of police officers online. The proposal is part of Macron's initiative to fight terrorism following a string of attacks by Muslim extremists.

Last week, Macron said his party was willing to rewrite the terms of the proposed bill to bar images posted online whose intent was to cause "physical and psychological" harm to police officers. Some critics argue the proposed changes aren't enough.

"We're heading toward an increasingly significant limitation of freedoms. There is no justification," one protester said.
