North Korea has fired three ballistic missiles towards the Sea of Japan, according to the South Korean military.

The missiles were launched early on Tuesday local time from the western city of Hwangju and flew between 311 and 373 miles towards the Sea of Japan.

In a statement, the South Koreans said: “The ballistic missiles flight went from 500 kilometers to 600 kilometers, which is a distance far enough to strike all of South Korea including Busan.”

Busan is a South Korean port city in the south.

These are not the first missiles North Korea has fired in recent months – intermediate-range missiles were tested in June and a submarine launched a missile earlier this month.

Just days ago, South Korea and the US announced they would deploy the Terminal High Altitude Area Defence anti-missile system to defend the South from the North.
