Yonhap: North Korea test-fires missiles

SEOUL, South Korea (CNN) - North Korea test-fired what appeared to be two short-range missiles off its east coast on Thursday, South Korea's Yonhap news agency reported.

"One was fired at 5:20 p.m. and the other at 6 p.m. from Sinsang-ni," near the eastern coastal city of Wonsan, South Korean defense ministry spokesman Won Tae-jae said, according to Yonhap.

The launch was expected. The North Korean government issued a warning to mariners to avoid an area in the Sea of Japan at certain times between June 24 and July 9 because of a "military firing exercise," according to a U.S. military communication about the warning provided to CNN.

The North issued a similar warning before testing a long-range missile in April, but that warning indicated two potential danger areas more indicative of a long-range missile test.
