Police yesterday manned checkpoints on roads leading in and out of the city, while squads of officers checked the identity papers of people on the street and conducted searches for explosives in subway stations, outdoor markets, apartment buildings, and other areas. Putin said he did not believe there was a need to impose a state of emergency to combat the attacks. Putin urged the creation of a security cordon to contain possible threats coming from the breakaway republic of Chechnya, which borders Dagestan. No one has claimed responsibility for the Moscow attacks nor a blast in Dagestan earlier this month which killed 64 people.
Authorities say they have detained three suspects, but few other details have been released.
