North Korea launched an intermediate-range ballistic missile into the East Sea on Monday, South Korea's military said, as U.S. Secretary of State Antony Blinken arrived in Seoul amid a political crisis in the country.

North Korea has fired what appears to be an intermediate range ballistic missile towards the sea to its east, South Korea's military said, in what is Pyongyang's first missile launch in two months. Japan's defence ministry said around noon local time (03:00 GMT) that the projectile had already fallen into the sea.

U.S. Secretary of State Antony Blinken said a North Korean missile test carried out during his visit to Seoul on Monday was a reminder of the need to deepen Washington's cooperation with South Korea and Japan to deter an emboldened Pyongyang.
