Burma's state-run newspaper says terrorists detonated a time bomb on a passenger bus east of Rangoon.
The "New Light of Myanmar" reports that the bomb exploded an hour after the bus arrived at the station in Mawlamyine in Mon state Tuesday morning. The bomb ripped a hole in the side of the bus but did not harm the driver or two passengers.
The newspaper says authorities investigating the blast are linking it to terrorists trying to upset the country's stability.
In the past, Burma's military government has blamed small bomb attacks on exile groups opposed to military rule.
Some dissidents say the blasts are carried out by government-linked groups to justify tighter security.
Burma has been under military rule since 1962.
