The top five Twitter-owned social media sites, along with YouTube, have been blocked in Russia for violating the country’s “gay propaganda law,” a spokesperson for the Federal Security Service (FSB) told journalists on Wednesday.
The Russian Information Agency said that “Twitter has not been able to comply with Russian law.”
The FSB also said that Facebook and YouTube have not been allowed to operate under Russian jurisdiction.
In July, Russian authorities banned social media networks including Facebook and Twitter, with the intention of protecting children from sexually explicit content.
The move was seen as an attempt to crack down on what it described as “harmful” content.
Twitter was also blocked in Ukraine in September 2016 for failing to remove “harmfully offensive content” within 24 hours of being reported.
In January, the FSB warned of a “crisis of social media” in Russia.
The Kremlin has repeatedly claimed that it is trying to combat gay propaganda and gay rights abuses by blocking the sites and removing the accounts of the individuals involved.
In August, the Russian authorities announced that they would be banning the websites from operating within Russia.
Russian authorities have also imposed a ban on the VKontakte social network, a popular social network in Russia that has over 1.5 million members.
