US announces new sanctions against North Korea

The US will impose new sanctions on North Korea, following the crisis over the sinking of a South Korean warship.

The move was announced by Secretary of State Hillary Clinton during a visit to South Korea.

She said the measures would target Pyongyang's sale and purchase of arms and import of luxury goods, and would help prevent nuclear proliferation.
