Suicide bombers attack Moscow subway

Edited by John Stokes

At least 38 people confirmed dead, 64 injured in suicide attacks on two Moscow subway stations.

Packed rush hour trains were attacked at Lubyanka and Park Kultury stations; two female suicide bombers suspected.

Federal Security Service blames Islamist insurgents from North Caucasus; Russian government vows retaliation.

Attacks refocus domestic political agenda on security issues, and likely renewed Russian crackdown on separatist groups.
