N Korea rocket was home made

The long-range rocket launched by North Korea last month was largely made using domestic technology, South Korea said yesterday.
December's launch - condemned by its neighbours as a banned missile test - successfully put North Korea's first satellite in space.
International sanctions prevent North Korea importing advanced technology.
Correspondents say the discovery it was able to produce the "vast majority" of the parts without foreign help will be a cause for concern.
North Korea says the rocket carried a communications satellite into space.
