Rebel fighters with the Shan State National Army in Burma have joined forces and merged with the Shan State Army, in an effort to reinvigorate their five-decade struggle for independence against Burma's military government.

The merger effectively breaks a 10-year cease-fire between the Shan State National Army and Rangoon.

Military leaders from the rebel groups agreed to join forces at a ceremony Saturday in Doi Talaeng, a remote Shan State Army base along the Burma-Thailand border. They called on ethnic Shan people in Burma and overseas to stand united and fight the military.

There was no immediate public comment from the government in Rangoon.
