South Korean military officials say one of two missiles that were launched from North Korea on Monday morning likely crashed to the ground within the North's territory. They say the other one fell into the ocean.

Seoul's Joint Chiefs of Staff said the missiles were launched from South Hwanghae Province about 10 minutes apart. It said they were fired toward the northeast.

The first projectile was said to be a short-range ballistic missile that traveled about 600 kilometers. The second one traveled about 120 kilometers, but officials said they have not yet determined its type.

The officials say the missile that crashed into the ground flew erratically right from liftoff.

The North last Wednesday launched a ballistic missile toward the Sea of Japan, claiming it had successfully conducted the separation and guidance test of multiple warheads. But South Korea believes the launch failed.

Pyongyang on Sunday denounced a joint exercise that Japan, the United States and South Korea conducted last week. It described the so-called "Freedom Edge" drill as "provocative," saying that such an action could lead to "fatal consequences."

Japan's Chief Cabinet Secretary Hayashi Yoshimasa said there are no reports of the missiles landing inside Japan's exclusive economic zone.
