The head pastor of one of Canada's largest congregations, who has been detained by North Korea since February, appeared before media in Pyongyang and admitted to allegations against him, a spokeswoman for his Toronto-area church said on Thursday.

The Rev. Hyeon Soo Lim, from the 3,000-member Light Korean Presbyterian Church in Toronto, was seen on video apparently confessing to crimes in front of reporters, said church spokeswoman Lisa Pak.

"There was a press conference in Pyongyang, and he was asked to go and say some statements about his allegations and charges. The Chinese media and the state media were there," Pak said.
