MOSCOW (AFP) - Police in central Russia have ordered local teachers to report on students who join opposition parties and commit other “extremist” acts, teachers and education officials said on Thursday. The letter from the regional police in the Ulyanovsk region to the local education department was sent earlier this month, according to copies of the text published online. The letter told the education department to instruct teachers “to inform interior ministry authorities about underage children who join public organisations, extremist movements and groups, and other informal youth organisations.”
