An explosion has killed 10 people - including at least two children - at a Moscow market, Russian officials say. At least 31 other people were injured in the blast at 1030 (0630GMT) at the eastern Cherkizovsky market. It brought down a two-storey building.
There are conflicting reports about the cause of the explosion.
According to Moscow's First Deputy Mayor Vladimir Resin, a "makeshift explosive device" blew up. Earlier police blamed a faulty gas cylinder.
Latest reports from Moscow police say a bomb had been hidden in a bag and left in a cafe.
According to some witnesses, there were two explosions at the market.
"As far as I know, there was one explosion, but the way I see it, it was not an accident but a premeditated act," Mr Resin told Russia's Itar-Tass news agency.
