North Korea fired around 10 artillery rockets from its multiple launch system earlier this week, coinciding with a joint visit by the U.S. and South Korean defense ministers to the Demilitarized Zone (DMZ), South Korea’s military said on Tuesday.

U.S. Defense Secretary Pete Hegseth arrived at Osan Air Base in South Korea on Monday for talks with Defense Minister Ahn Gyu-back, with discussions expected to focus on possible adjustments to the U.S.–South Korea alliance and regional security coordination.
