SEOUL, South Korea (AP) - North Korea fired five ballistic missiles off its eastern coast Saturday, South Korea said, a violation of U.N. resolutions and an apparent message of defiance to the United States on its Independence Day.
The launches, which came two days after North Korea fired four short-range cruise missiles, will likely further escalate tensions in the region as the U.S. tries to muster support for tough enforcement of the U.N. resolution imposed on the communist regime for its May nuclear test.
South Korea's Joint Chiefs of Staff said three missiles were fired early Saturday, followed by two more in the afternoon. The Defense Ministry said that the missiles were ballistic and are believed to have flown more than 250 miles (400 kilometers).
South Korea's Yonhap news agency quoted military officials as saying the missiles appeared to be a type of Scud missile. North Korea's Scuds are considered short-range, the South's military said.
North Korea is not allowed to fire Scuds, medium-range missiles or long-range missiles under a resolution that bans any launch using ballistic missile technology. Thursday's launches, on the other hand, did not violate the resolution as they were cruise missiles rather than ballistic, according to South Korea's Foreign Ministry.
Ballistic missiles are guided during their ascent out of the atmosphere but fall freely when they descend. Cruise missiles are fired straight at a target.
The North has a record of timing missile tests for the U.S. national day, which fell on Saturday.
«The missiles were seen as part of military exercises, but North Korea also appeared to have sent a message to the U.S. through the missile launches,» South Korea's presidential official said, without elaborating.
A senior presidential official told The Associated Press the missiles fired on Saturday are believed to have a range of less than 300 miles (500 kilometers).
The official warned that North Korea could fire more missiles in coming days, but said there was little possibility it could fire the intercontinental ballistic missile it threatened in April.
He spoke on condition of anonymity because he was not authorized to speak to media.

«Our military is fully ready to counter any North Korean threats and provocations based on strong South Korea-U.S. combined defense posture,» the Joint Chiefs of Staff statement said.
North Korea's state news agency carried no reports on the launches. But the North had warned ships to stay away from its east coast through July 10 for military exercises _ an indication it was planning launches.
The chief of U.S. Naval operations, Adm. Gary Roughead, said Saturday the American military was ready for any North Korean missile tests.
«Our ships and forces here are prepared for the tracking of the missiles and observing the activities that are going on,» Roughead said after meeting Japanese military officials in Tokyo.
