North Korea fires ballistic missile as top US diplomat visits Seoul

North Korea fired a ballistic missile on Monday, Seoul's military said, as US Secretary of State Antony Blinken visited South Korea to meet top officials and attend a democracy summit. 

Blinken is in Seoul for the third Summit for Democracy, an initiative of US President Joe Biden, which the South is hosting this week, and is set to meet his Korean counterpart on the sidelines for talks.

"North Korea fired an unspecified ballistic missile toward the East Sea," Joint Chiefs of Staff said.
