The United States, Japan and South Korea will hold two days of missile tracking drills starting on Monday, Japan’s Maritime Self-Defence Force said, as tensions rise in the region over North Korea’s fast-developing weapons programmes.

The United States and South Korea conducted large-scale military drills last week, which the North said made the outbreak of war “an established fact”.
