South Korea salvages wreckage from North Korea's failed rocket launch.

South Korea has salvaged part of a rocket used in North Korea's failed attempt to launch its first military satellite last month. The rocket crashed into the sea during the flight. The South Korean military is continuing its search for additional objects from what the North has claimed was a space launch vehicle. North Korea has been rapidly modernising its military arsenal, with leader Kim Jong Un promising to put its first spy satellite into orbit as part of his military development programme.
