Russian authorities have detained two people for questioning over a fire at a market warehouse in Moscow that killed 17 migrant workers on April 3.
Russian media has reported that the two were the owner of the Kachalovsky market, Vladimir Lykov, and the individual who had rented it and hired the migrant workers there, Sedrak Stepanyan.
Officials are still identifying the victims, who had turned the back of the building into a sleeping area.
There has been confusion over whether the victims were from Uzbekistan and Tajikistan.
Millions of migrants from poor former Soviet republics work on construction sites or do menial jobs in Russia.
It is still unclear what triggered the fire.
