A law that aims to protect children from harmful internet content by allowing the government to take sites offline has taken effect in Russia.
The authorities are now able to blacklist and force offline certain websites without a trial.
The law was approved by both houses of parliament and signed by President Vladimir Putin in July.
Human rights groups have said the legislation might increase censorship in the country.
The law is the amendment to the current Act for Information.
The authorities say the goal is to protect minors from websites featuring sexual abuse of children, offering details about how to commit suicide, encouraging users to take drugs and sites that solicit children for pornography.
If the websites themselves cannot be shut down, internet service providers (ISPs) and web hosting companies can be forced to block access to the offending material.
Critics have described it another attempt by President Vladimir Putin to exercise control over the population.
“Of course there are websites that should not be accessible to children, but I don’t think it will be limited to that,” Yuri Vdovin, vice-president of Citizens’ Watch, a human rights organisation based in Saint-Petersburg, told the BBC.
“The government will start closing other sites – any democracy-oriented sites are at risk of being taken offline.
“It will be [an attack on] the freedom of speech on the internet.”
Mr Vdovin said that to close a website, the government would simply have to say that its content was “harmful to children”.
“But there are lots of harmful websites out there already, for example, fascist sites – and they could have easily been closed down by now – but no, [the government] doesn’t care, there are no attempts to do so,” he added.
A risk for websites?
Besides NGOs and human rights campaigners, websites including the Russian search engine giant Yandex, social media portal Mail.ru and the Russian-language version of Wikipedia have all protested against the law.
