President Dmitry Medvedev is quoted as saying laws must be toughened for terrorist accomplices, regardless of their level of involvement, after 39 people were killed in double suicide bombings of the Moscow subway.
Russian news agencies quote Medvedev as saying the country needs the kind of model whereby any accomplice, "no matter what he does — be it cook the soup or wash the clothes" for terrorists, has committed a crime.
Russian authorities have faced pressure to react in the wake of Monday's attacks and follow-up blasts in the southern region of Dagestan on Wednesday.
Medvedev and Prime Minister Vladimir Putin have called on the terrorists to be unceremoniously destroyed.
A Chechen militant leader claimed responsibility for the bombings in Moscow.
