SEOUL, South Korea — North Korea launched seven ballistic missiles Saturday into waters off its east coast in a show of military firepower that defied U.N. resolutions and drew global expressions of condemnation and concern.

The salvo, confirmed by the South Korean government, also appeared to be a slap at the United States as Washington moves to enforce U.N. as well as its own sanctions against the isolated regime for its May 25 nuclear test.

The launches came on July 4, which is U.S. Independence Day. The display was similar to one that took place three years ago, also while Americans celebrated the Fourth of July during another period of tensions over Pyongyang’s nuclear weapons program.

The number of missiles was the same, though in 2006 North Korea also launched a long-range rocket that broke apart and fell into the ocean less than a minute after liftoff.

South Korea said Saturday’s missiles likely flew more than 250 miles, apparently landing in waters between the Korean peninsula and Japan.

South Korea and Japan both condemned the launches, with Tokyo calling them a “serious act of provocation.” Britain and France issued similar statements.

Russia and China, both close to North Korea, expressed concern over an “escalation of tension in the region,” the Russian Foreign Ministry said in a statement after a meeting in Moscow.

In Washington, the White House had no immediate comment. But two senior officials in President Barack Obama’s administration, speaking in advance of the launches, said any reaction was likely to be muted to avoid giving attention to Pyongyang or antagonize it. They spoke on condition of anonymity because they were not authorized to discuss the matter publicly.

North Korea has engaged in a series of acts this year widely seen as provocative. It fired a long-range rocket it said was a satellite in early April, and in late May it carried out its second underground nuclear test following the first in late 2006.

The country has also stoked tensions with rival South Korea and last month threatened “thousand-fold” military retaliation against the U.S. and its allies if provoked.

In addition, North Korea convicted two American journalists last month and sentenced them to 12 years hard labor for illegally entering the country. It is also holding a South Korean worker for allegedly denouncing its political system.

The secretive communist country is believed undergoing a political transition in which 67-year-old leader Kim Jong Il appears to be laying the groundwork to transfer power to one of his sons. Kim himself took over from his late father, the country’s founder.

South Korean officials said Saturday’s launches came throughout the day and were part of military exercises. The North, which had warned ships to stay away from waters off the east coast through July 10, also fired what are believed to have been four short-range cruise missiles Thursday.

Speculation had been building for weeks that the launches were coming. The key question has been whether the North might fire an intercontinental ballistic missile, as it vowed to do in late April.

Despite a Japanese newspaper report last month that one might be launched toward Hawaii in early July, U.S. officials have noted no such preparations, which are complex, usually take days and are often observable by spy satellites. Still, that hasn’t stopped Washington from boosting missile defenses as a precaution.

South Korea’s Yonhap news agency suggested launch activity may be winding down, at least for now. It reported late Saturday, citing an unidentified military official, that the North was pulling personnel from its missile launch site and allowing ships to sail again off the coast. The Defense Ministry said it could not confirm the report.

North Korea’s state news agency did not mention the launches.
