North Korea 'fires ballistic missile' after Seoul demands apology

North Korea launched a ballistic missile toward the sea off its east coast on Saturday, according to military officials in South Korea and Japan. The launch occurred just days after South Korea demanded an apology from Pyongyang regarding a recent explosion within the Demilitarized Zone (DMZ) that injured three South Korean soldiers.

Pyongyang has denied responsibility for the DMZ blast, which occurred last month, and has rejected South Korea's accusations. The missile launch follows a period of heightened tensions between the two nations as they continue to dispute the cause of the border incident.
