Burma's state-run newspaper reports that a man was killed Saturday while trying to plant a bomb in a mosque.
The New Light of Myanmar report called the man a "terrorist," but did not say which organization he belonged to.
The news comes on the same day as another official report warned that organizations the All Burma Students' Democratic Front and Vigorous Burmese Student Warriors, dubbed terrorist groups by the military-ruled regime, sent nine individuals into the country at the end of last month to launch terrorist missions.
Official reports say the government is also stepping up its security measures, and urging the public to expose what it calls the subversive acts of terrorist operatives.
Last month, a letter bomb exploded inside a post office in Rangoon, injuring one man.
Burma has been under military rule since 1962.
