Russia has added former chess champion and exiled Kremlin critic Garry Kasparov to its state list of “terrorists and extremists," Paralel.Az reports citing The Moscow Times.

While state financial watchdog Rosfinmonitoring did not specify the reason for Kasparov being added to the list, he has been a vocal critic of President Vladimir Putin for years and has condemned Moscow’s military aggression in Ukraine since 2014.

Kasparov, who retired from playing chess in 2005 to devote his time to politics and activism, once called Putin “the world’s most dangerous man.”

Being added to Russia's lists of “extremists and terrorists” allows the authorities to freeze designees’ bank accounts without a court order.
