North Korea sentences US citizen to 15 years' hard labour

North Korea says it has sentenced a US citizen to 15 years of hard labour for what it describes as "anti-government crimes".

The announcement, from state news agency KCNA, said Pae Jun-ho, known in the US as Kenneth Bae, was tried on 30 April.

He was held last year after entering North Korea as a tourist.

The move comes amid high tensions between North Korea and the US, after Pyongyang's third nuclear test.
