Iain Clayton, the husband of Laura Ling, said Wednesday his wife called him on Sunday night. He said although she tried to be strong on the phone, she sounded scared.
Clayton spoke after a vigil at San Francisco's Academy of Art University for Ling and Euna Lee, the other American reporter jailed in North Korea.
He says Ling's medical condition has deteriorated and Lee has developed a medical problem. Ling reportedly suffers from an ulcer.
Lee and Ling have been sentenced to 12 years of hard labor.
Michael Saldate, Lee's husband, said he heard from his wife Sunday as well. He said she, too, sounded scared.
