Quoting multiple sources, Japan’s Sankei Shimbun (via the Chosun Ilbo)—admittedly, not always the most reliable source—reports that North Korea has informed foreign diplomats in Pyongyang that it would launch a missile over Japan into the Pacific sometime around tomorrow.

The paper said North Korea told certain diplomats the test—and the unpredictable situation that may follow—was the reason Pyongyang advised foreign diplomats to evacuate North Korea.

The Chosun Ilbo notes that the South Korean government believes the North will fire off a Musudan missile (range: 3,000–4,000 km) sometime soon (today at the earliest), citing a dramatic increase in North Korean communications along the East Sea coast.

Oh, and if the North does decide to fire a missile off, Sen. John McCain thinks we should shoot it down. Just to make a point. I’m guessing this won’t happen, as the Pentagon is apparently keen to cool things down in Korea.

UPDATE: The Pentagon is saying it won’t shoot down the missile if it’s heading for open water.

Oh, and interestingly enough, a commenter at GI Korea suggests that China might have supplied North Korea’s mobile missile launchers, citing a column by Gordon Chang.
