SEATTLE (AP) -- The family of an American missionary held more than a year in North Korea was heartbroken and encouraged by a brief news conference in which Kenneth Bae, wearing a gray cap and inmate's uniform with the number 103 on his chest, apologized and said he committed anti-government acts.
"My brother is not a number to me, or to the rest of his family," his sister Terri Chung of Edmonds, Wash., said in a statement Monday. "He is a kind and loving husband, father, son and brother -- and needs to be home immediately."
Chung also apologized to North Korea and pleaded for it to release Bae, saying the family is concerned for his health and she could "see that he was distressed."
"Our family sincerely apologizes on Kenneth's behalf," she said. "We humbly ask for your mercy to release my brother."
Family friend Derek Sciba told The Associated Press that Bae has chronic health problems.
"On the one hand it's heartbreaking to see him in a prison uniform at the mercy of folks in North Korea, but on the other hand it's encouraging to see him and that he's able to speak," Sciba said. He is a friend of Chung's and part of a group pushing for Bae's release.
Bae made the comments at what he called a press conference held at his own request. He was under guard during the appearance. It is not unusual for prisoners in North Korea to say after their release that they spoke in similar situations under duress.
Bae spoke in Korean during the brief appearance, which was attended by The Associated Press and several other members of the foreign media in Pyongyang.
Bae, the longest-serving American detainee in North Korea in recent years, expressed hope that the U.S. government will do its best to win his release. He said he had not been treated badly in confinement.
"I believe that my problem can be solved by close cooperation and agreement between the American government and the government of this country," he said.
Bae was arrested in November 2012 while leading a tour group and accused of crimes against the state before being sentenced to 15 years of hard labor. He was moved to a hospital last summer in poor health.
He made an apology Monday and said he had committed anti-government acts.
Bae said a comment last month by U.S. Vice President Joe Biden had made his situation more difficult.
"The vice president of United States said that I was detained here without any reason," Bae said. "And even my younger sister recently told the press that I had not committed any crime and I know that the media reported it.
"I think these comments infuriated the people here enormously. And for this reason, I am in a difficult situation now. As a result, although I was in medical treatment in the hospital for five months until now, it seems I should return to prison. And moreover there is greater difficulty in discussions about my amnesty."
Bae's appearance came weeks after North Korea freed an elderly American veteran of the Korean War who had been held for weeks for alleged crimes during the 1950-53 conflict.
State media said 85-year-old Merrill Newman was released because he apologized for his wrongdoing and that authorities also considered his age and medical condition. Newman said after his release that a videotaped confession was made under duress.
Chung thanked the U.S. government for its efforts so far, but called for an increased push to secure Bae's release.
"We implore Secretary Kerry and President Obama to take immediate action to bring Kenneth home," she said.
In Washington, State Department spokeswoman Jen Psaki said the U.S. government was continuing to work with the Swedish Embassy to secure Bae's release.
"As we have said before, we remain very concerned about Kenneth Bae's health," Psaki said. "We continue to urge the DPRK authorities to grant Bae amnesty and immediate release."
North Korea has detained at least seven Americans since 2009. They were eventually deported or released without serving out their terms, some after prominent Americans such as former presidents Bill Clinton and Jimmy Carter traveled to Pyongyang.
A senior U.S. envoy had planned to visit North Korea in late August to discuss Bae's release, but Pyongyang withdrew its invitation at the last minute, accusing the United States of hostility. Analysts said North Korea was apparently trying to gain leverage in a long-running international standoff over its nuclear weapons program.
