Georgian officials say they have arrested two residents of Abkhazia, alleging they were preparing a terrorist bombing for Russia.
Georgian Interior Ministry spokesman Shota Utiashvili said the man and woman were seized on Thursday carrying explosives to be set off in a market.
He added that the suspects said they were acting on the orders of Russian special services.
Russia's Federal Security Service declined immediate comment Friday. But the ITAR-Tass news agency cited Abkhazian police official Vadim Gvindzhia as saying the arrest was "a spectacle staged by Georgian special services."
Abkhazia and South Ossetia broke free of Georgian control in the 2008 war between Georgia and Russia.
