DUSHANBE, Tajikistan: Tajikistan on Wednesday denounced an “ethnic hatred” attack in Russia, in a rare criticism of its ally a day after a 10-year-old Tajik schoolboy was killed by an older pupil near Moscow. Russia’s main investigative body, the Investigative Committee, said the 15-year-old suspect was detained and in custody after the attack in Gorki-2, a village west of Moscow in the Odintsovo district. Authorities in Dushanbe confirmed the victim was Tajik and summoned the Russian ambassador to protest the attack.
