North Korea fired an unspecified ballistic missile toward the East Sea on Sunday, South Korea's military said.

The Joint Chiefs of Staff (JCS) said it detected the launch but did not give further details.

The launch came two days after South Korea's First Deputy National Security Adviser Kim Tae-hyo said the North could fire an intercontinental ballistic missile within this month.

The North last fired a ballistic missile on Nov. 22, but the launch apparently failed, according to the JCS.
