North Koreans mark rocket success

North Koreans have gathered in Pyongyang for a mass rally to celebrate Wednesday's long-range rocket launch.

State television showed huge crowds cheering to mark the launch, which has been condemned by many nations as a banned test of missile technology.

South Korea, meanwhile, says it has retrieved debris from the rocket and will study it to assess its technology.

The first stage of the rocket fell west of the Korean peninsula. South Korea's navy located it shortly afterwards.
