Myanmar has blamed ethnic Karen rebels for a bombing on a passenger train last month that killed two people.
The state-run New Light of Myanmar reported Thursday that a suspect was arrested in Karen state 10 days after the May 19 bombing. The report said he confessed he was assigned by senior members of the Karen National Union and provided with explosives. The group has not commented.
The bomb exploded on a train near the capital Naypyitaw, and nine people were wounded.
Bombings are rare but not unknown in Myanmar, where pro-democracy activists and ethnic groups are at odds with the military-backed regime. The government usually blames opposition militants, but most remain shrouded in mystery.
