NAMTEE, Myanmar - Pro-democracy leader Aung San Suu Kyi appealed for unity among Myanmar’s disparate ethnic groups Thursday as she hit the campaign trail in the country’s conflict-riven far north. Thousands of people greeted the Nobel Peace Prize laureate in northernmost Kachin state, where bloody fighting between government troops and ethnic minority guerrillas has displaced tens of thousands of people since mid-2011. “We cannot forget that our country is a union,” Suu Kyi said in a speech in the town of Namtee to drum up support for her National League for Democracy party.
