SEOUL -- Tensions have soared between North and South Korea recently, as Pyongyang responds with threats over propaganda leaflets floated northward over the border by defectors. That has made many of the 35,000 or so North Koreans who have sought refuge in the South nervous.
"We are feeling heartbroken, wondering what will happen to our families and relatives in North Korea," said Kim Tae-san, who heads a conservative group of defectors and others called the One Korea Work Together.
