YANGON - Myanmar's military has used heavy weapons to overrun remote rebel camps in northern Kachin state, the army said Friday, as a seasonal offensive ramps up the long-running conflict. A separate military campaign in Rakhine state, which has forced 655,000 Rohingya Muslims over the border into Bangladesh, has dominated global attention. But the conflict in Kachin, a mainly Christian state in the Buddhist-majority country, has rumbled on away from international headlines and fighting is again intensifying now that monsoon rains have ended.
