A barrage of ballistic missiles that North Korea test-fired over the weekend may have included a new type of a Scud with an extended range and improved accuracy that poses a threat to Japan, a South Korean newspaper reported Monday.
Pyongyang launched seven missiles into waters off its east coast Saturday in a show of force that defied U.N. resolutions and drew international condemnation.
On Monday, South Korea's mass-circulation Chosun Ilbo newspaper reported the launches were believed to have included three Scud-ER missiles with a range of up to 620 miles (1,000 kilometers).
The paper said the Scud-ER has a longer range and better accuracy compared with previous Scud series so is "particularly a threat to Japan."
The Chosun Ilbo, citing a government source it did not name, said the other four missiles were two Scud-C missiles with a range of 310 miles (500 kilometers) and two medium-range Rodong missiles that can travel up to 810 miles (1,300 kilometers).
Five of the seven missiles flew about 260 miles (420 kilometers) from an eastern coastal launch site and landed in one area, meaning their accuracy has improved, the paper said.
South Korea's Defense Ministry said it could not confirm the report, saying details of the launches were still under investigation.
One Defense Ministry official told The Associated Press on Sunday that the missiles were likely capable of striking key government and military facilities in South Korea, and that they appeared to have traveled about 250 miles (400 kilometers). The official spoke on condition of anonymity citing department policy.
The launches on July 4 — the U.S. Independence Day holiday — also appeared to be a poke at Washington as it moves to enforce U.N. as well as its own sanctions against the isolated regime for its May 25 nuclear test.
Adm. Mike Mullen, chairman of the U.S. Joint Chiefs of Staff, warned they were "very destabilizing, potentially."
