The Swedish government backed a court ruling not to extradite to Russia Aslan Adayev, 39, citing human rights violations in the country, including in its North Caucasus Republic of Chechnya.
"The position of the Swedish authorities is nothing but political hypocrisy, an attempt to divide terrorists into good and bad... Stockholm willingly or unwillingly is sending a signal that Sweden could be a harbor for terrorists," the Russian Foreign Ministry said on its website.
"The verdict of the Swedish Supreme Court dismisses as 'merely political' all charges laid against Adayev, including terrorism, conspiracy to kill police officers, illegal possession of arms and arms trafficking," the ministry's website said.
Last year, Stockholm refused to extradite another Chechen, Magomed Uspayev, suspected of involvement in the abduction and murder in Chechnya of a Russian photo journalist in 1999.
