A former mayor of the provincial capital of North Ossetia has been shot dead in his car by unidentified gunmen.
Kazbek Pagiyev died of multiple gunshot wounds in Wednesday's attack in Vladikavkaz, the Russian interior ministry said.
The assassination comes weeks after his successor in the post was also killed, police said.
Pagiyev's driver died in the shooting.
Pagiyev, who stood down as deputy prime minister in North Ossetia last week, had previously served as the mayor of Vladikavkaz.
He was replaced by Vitaly Karayev, who was killed by an armed man last month.
Provinces in Russia's north Caucasus have been troubled by unrest linked to fighters based in the neighbouring province of Chechnya, a police crackdown on clan rivalries and internal power struggles.
