S. Korea says rocket believed to have exploded

South Korea says a rocket that it sent into space Thursday carrying an observation satellite is believed to have exploded in flight.

Minister of Education, Science and Technology Ahn Byong-man says officials believe the two-stage Naro rocket operated normally for 137 seconds after liftoff from the country's space center. But then communications with the rocket were lost. He says: "We believe that the Naro rocket exploded." (AP)
