North Korea confirms rocket launch failure
North Korea's keenly-watched rocket launch has failed, Pyongyang has confirmed.
The rocket - seen by many as a banned test of long-range missile technology - was launched from north-west North Korea early on Friday.
The US, Japan and South Korea say it flew only for a short time before breaking up and crashing into waters off the Korean peninsula.
North Korea said its scientists were assessing what had caused the failure.
