BANGKOK (AP) — The main underground group coordinating resistance to Myanmar’s military government called for a nationwide uprising on Tuesday. There were no immediate signs of heightened resistance activity, although some student groups and ethnic armed organizations expressed solidarity. The National Unity Government is popular inside Myanmar, but its actual power and influence is hard to measure. He said people should help the defense forces where they can, including with information about government military forces. The resistance movement against the military takeover had established “people’s defense forces” in many areas, but they mostly operate locally and when active, carry out small-scale hit-and-run guerrilla operations.
