MOSCOW — A close associate of a former Russian defense minister was placed under house arrest on Friday on charges of defrauding the country of millions of dollars.

Yevgeniya Vasilyeva, the 33-year-old former head of the Defense Ministry’s property department, is accused of stealing more than $11 million through a scheme that involved the sale of the military’s prized real estate, Russia’s top investigative agency said. Vasilyeva faces up to six years in prison if convicted.
