Russia vs Tadjik

MOSCOW — The imprisonment of a Russian citizen in Tajikistan has touched off reprisals against ethnic Tajik migrant workers in Russiawho say they have been unjustly targeted for arrest and deportation.

Immigration agents have rounded up at least 300 ethnic Tajiks in the last two weeks, according to the Federal Migration Service, though independent human rights workers said they believed that hundreds more might have been detained. Tajik officials said the first deportees began arriving home this week, though it was unclear how many would ultimately be expelled.
