BANGKOK (AP) — Ethnic guerrillas say they captured a Myanmar army base near the border with Thailand. It’s a morale-boosting action for those who oppose the Myanmar military’s takeover of the central government in February. A spokesman for the Karen National Union said the group’s armed wing attacked the base early Tuesday and burned it down. Hours later, Myanmar’s military staged airstrikes on villages in territory controlled by the Karen forces. The Karen minority’s main political group seeks greater autonomy, and controls territory in eastern Myanmar near the Thai border. It’s a close ally of the resistance movement against the military’s ouster of the elected government of Aung San Suu Kyi in February.
