Rebel forces claim to have captured key Thai-Myanmar border town Myawaddy

In a major setback for Myanmar's military, rebel forces have claimed to have captured a key town near the Thai border. It is the latest in a string of defeats, as the army battles ethnic armed groups on multiple fronts. The Karen National Union, which has long fought against the military, said it has been leading the attack on Myawaddy. The town is a major crossing point for trade with Thailand.
