North Korea Fires Missile Over Japan
The missile, launched early on Tuesday Korean time, flew over Hokkaido island before crashing into the sea.
The UN Security Council is to hold an emergency meeting later in response.
North Korea has conducted a flurry of missile tests recently amid growing international unease.
This is the first time it has fired what is thought to be a ballistic weapon over Japan. On the two previous occasions its rockets crossed Japan – in 1998 and 2009 – North Korea said they were for satellite launch vehicles, and therefore not weapons.
