SEOUL - North Korea carried out “another important test” towards the development of a reconnaissance satellite, state media said Sunday, but analysts warned it was a thinly-veiled ballistic missile launch, just days before South Korea elects a new president.From hypersonic to medium-range ballistic missiles, Pyongyang test-fired a string of banned weaponry in January and last week launched what it claimed was a component of a “reconnaissance satellite” -- although Seoul described it as another ballistic missile. North Korea is under biting international sanctions for its nuclear weapons programs, but peaceful satellite launches are not subject to the same level of restrictions -- although they use much of the same technology.
