A man died after blowing himself up with a grenade near a supermarket in south-east Moscow, Russian news agencies said. No other injuries were reported.
Police had no immediate official comment and reports from unidentified witnesses and police sources gave contradictory accounts of the blast. There was no immediate indication of whether it was intended as a terrorist act.
The Interfax news agency cited witnesses as saying the man drove alongside a discount retail supermarket, got out of the car and went up to the store's entrance muttering unintelligibly, then pulled out the grenade and set it off. Other reports said he was either in the car or next to it.
A suicide bomber killed 37 people in an attack on 24 January at Moscow's Domodedovo airport, the country's busiest. A leader of Islamist insurgents in Russia's Caucasus claimed responsibility for ordering that attack.
