Two suspected Chechen suicide bombers wearing belts laden with explosives were arrested in Moscow today.
Federal Security Service officials and a bomb squad were sent to a market in the south of the Russian capital where the men, aged between 22 and 25, were held, Interfax news agency reported.
Interfax said the explosives they were wearing also contained metal balls.
During the October hostage crisis at a Moscow theatre, women who were among the Chechen rebel attackers were shown in television footage wearing belts presumed to be filled with explosives attached to handheld detonators.
Searching for accomplices after that siege ended, Russian authorities have said they have confiscated other such belts.
