North Korea says it has begun fuelling its rocket ahead of a planned - widely criticised - launch later this week.
Paek Chang-ho, head of the satellite control centre of the Korean Committee of Space Technology, said fuel was being injected "as we speak".
He did not confirm the exact timing of the launch, but it is expected between 12-16 April.
Pyongyang says the rocket will launch a satellite, but critics fear it is a test of long-range missile technology.
"We are injecting fuel as we speak. It has started," Mr Paek told visiting foreign journalists on the outskirts of the capital, Pyongyang.
The journalists were taken on Sunday to the Sohae satellite station at Tongchang-ri, on the country's north-west coast, to see the final preparations for the launch.
