Thai and Burmese officials say an attack on the site of a controversial hydropower dam project in Burma has killed a Thai worker.
Officials say the surveyor was killed Sunday at the site in Karen state.
Burmese state media blame Sunday's attack on the rebel Karen National Union, which has been fighting for greater autonomy from Burma's military government.
But the rebels told the Reuters news agency they believe Burmese troops carried out the attack to discredit their group.
The Electricity Generating Authority of Thailand is building the one-billion dollar dam. The company says it has evacuated its 42 remaining workers from the site.
Another worker died earlier this year after stepping on a landmine.
Environmentalists and rights groups say the dam project will tarnish the Salween River region and displace the area's ethnic minorities.
