North Korea launched a missile from a test facility near the country’s west coast early Sunday morning.

The launch came just days after South Koreans went to the polls to elect a new president.

The South Korean military says the missile flew about 435 miles, or 700 kilometers. The missile flew for 30 minutes before landing the Sea of Japan, Reuters said, citing a Japanese official.
U.S. officials said they were still assessing whether the launch was successful and trying to determine what kind of missile was tested. The last North Korean missile test on April 28 failed minutes after launch.

The flight was not consistent with an intercontinental ballistic missile, said Maj. Rob Shuford, a spokesman for the U.S. Pacific Command.

Although the type of missile is not known, the U.S. had been expecting the North to fire a KN-17 medium-range ballistic missile.

The North American Aerospace Defense Command (NORAD) determined the missile launch from North Korea did not pose a threat to North America.
