BRIEFLY North Korea ‘detains US citizen’

An American citizen has been detained in North Korea as he tried to leave the country, South Korean media say.

The man was identified only by his surname, Kim. He becomes the third American to be detained by the North; one has been sentenced for spying, the other for trying to steal a sign from a hotel.

The latest detention comes amid high tension on the peninsula, with the US warning its “strategic patience” on the North’s nuclear programme is over.
