North Korea announces long-range rocket launch

North Korea is to launch a long-range rocket between 10 and 22 December, its official news agency says.

The KCNA agency said the aim was to launch a satellite. Previous, unsuccessful launches have been criticised as breaches of a UN ban on North Korean ballistic missile tests.

The announcement is likely to increase tensions with North Korea's neighbours, with South Korea expressing concern over Pyongyang's announcement.
