Police have shot dead four teenagers who launched three attacks in and around the Chechen capital Grozny, say officials in the Russian republic.
A fifth teenager detonated a bomb he was carrying in a rucksack, but survived. He had approached a police post in Mesker-Yurt, east of Grozny.
No policemen died. In the past decade Chechnya has seen much jihadist unrest.
