(CBSNEWS) – North Korea launched a missile from a test facility near the country’s west coast early Sunday morning, U.S. officials tell CBS News national security correspondent David Martin.
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, according to Reuters. 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.
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, Martin reports.
