Burmese state media say members of an ethnic rebel group have surrendered their weapons to the government.
Thursday's reports said a 170-member unit of the Shan State National Army laid down its arms in a ceremony Tuesday in northwest Burma.
The rebel group reached a peace agreement with the government in 1995, but was allowed to keep their weapons for self-defense.
Insurgents from the Shan, Karen, Karenni, Mon and other ethnic minorities had been fighting for greater autonomy from the central government.
Since seizing power in 1988, Burma's military government has reached ceasefire agreements with 17 major ethnic rebel groups. About half a dozen have surrendered to government forces.
