The Democratic People's Republic of Korea (DPRK) fired three short-range missiles off its eastern coast in the morning of Saturday, South Korea's Yonhap News Agency reported.
According to a government official, the DPRK fired one additional short range missile from its eastern coast base in Wonsan at around 10:45 a.m. (0145 GMT), following two scud-type missiles fired from the same base between 08:00-08:30 a.m. (2300- 2330 GMT Friday), Yonhap said.
All the three missiles are estimated to have a range of 400-500 km, the official said, Xinhua reported.
The missile firing came two days after the DPRK test-fired four short-ranges off its eastern coast, which South Korean officials described as part of routine military drills.
"Although the missiles fired on Thursday appear to be part of routine military drills, the recent scud missiles seem to have political purposes as they were fired a day before the U.S. Independence Day," the official said.
The DPRK, since May, has been spotted with actions in preparation for firing a new mid-range missile, as well as scud missiles, Yonhap said.
The military authorities, however, said no sign has been observed from either its eastern Musudan-ri base or a new Tongchang-ri base on its west to conclude that an intercontinental ballistic missile launch is imminent.
In April, the DPRK threatened to test-fire an intercontinental ballistic missile in protest of the U.N. Security Council's presidential statement which "condemned" the DPRK's earlier long- range rocket launch.
