North Korea said Sunday it had sentenced detained American Matthew Miller to six years of hard labour for "hostile" acts against Pyongyang.

"He committed acts hostile to the (North) while entering the territory of the (North) under the guise of a tourist last April," the state-run Korean Central News Agency said in a statement.

Miller was arrested in April after he allegedly ripped up his visa at immigration and demanded asylum.
