A triple suicide bombing in the Chechen capital Grozny has left at least nine people dead and many more injured.
One man is reported to have blown himself up at a police post near the regional parliament, killing two officers.
Two others later set off devices nearby, as police and other emergency services rushed to the scene.
The attack in Grozny is one of the deadliest to hit the autonomous Russian region in recent years.
The blasts are suspected to have been carried out by Islamic separatists.
They have undermined efforts by Chechen leader Ramzan Kadyrov to portray the area as an island of security, where an Islamist insurgency, rooted in the Chechen wars, has spread to neighbouring Muslim provinces.
