North Korea's latest launches involved "two ground-to-ground missiles," state-run media reported Wednesday, as a large-scale military exercise being conducted by South Korea and the United States entered its third day.

The South Korean military had said that the North fired two short-range ballistic missiles from its west coast toward the Sea of Japan on Tuesday. The missiles did not land within Japan's exclusive economic zone, according to the Japanese government.

The North Korean military fired the missiles over "a medium range" from Jangyon in South Hwanghae Province and hit a target after they flew about 611 kilometers, the country's official Korean Central News Agency said.

A missile unit of the Korean People's Army conducted the drill to train its sub-units, according to KCNA.

North Korea has slammed U.S.-South Korea military drills as a "rehearsal" for war and invasion, and had warned against the latest exercise.

The 11-day Freedom Shield exercise, which started Monday, is the first large-scale springtime exercise in five years. It is aimed at strengthening response capabilities amid the North Korean nuclear and missile threats, according to the South Korean and U.S. militaries.
