North Korea launched seven ballistic missiles from its eastern coast July 4, the Yonhap news agency reported. The missiles appeared to be a Scud type, officials said, and are estimated to have a range of 248-310 miles. The missiles were fired toward the East Sea from the Gitdaeryong base in Gangwon Province. South Korean officials said that the missiles might have been Rodong missiles -- modifications of Scuds -- and that their flight distances might have been shortened on purpose.
