North Korea fired multiple rocket launchers on the 1st, when the South Korea-China summit was held, and again on the 3rd, when the defense Ministers of South Korea and the United States visited the Joint Security Area (JSA) at Panmunjom. The actions are a lower-tier provocation than ballistic or cruise missiles, but they amount to provocations timed to South Korea's key diplomatic and security schedule.
The Joint Chiefs of Staff (JCS) said on the 4th, "The military detected about 10 rounds each of multiple rocket launchers fired into the northern West Sea from North Korea at about 3 p.m. on the 1st and about 4 p.m. on the 3rd." Military authorities are known to assess that North Korea fired 240 mm multiple rocket launchers on both occasions. With a maximum range of 60 km, the 240 mm launchers are at the level of long-range artillery aimed at the Seoul metropolitan area.
North Korea's launches this time came about 30 minutes before the schedules of the South Korean president and the Ministry of National Defense Minister began. The launch time on the 1st was about 30 minutes before Lee Jae-myung met Chinese President Xi Jinping at Gyeongju National Museum for the South Korea-China summit, and the start of the launch on the 3rd was about 30 minutes before U.S. Secretary of Defense Pete Hegseth arrived at Camp Bonifas, a U.S. Forces Korea base.
Multiple rocket launchers are not ballistic missiles banned by the U.N. Security Council, but this suggests North Korea likely staged a show of force with rocket launchers timed to South Korea's diplomatic and security schedule.
An official at the Joint Chiefs of Staff (JCS) said, "Under the South Korea-U.S. combined defense posture, the military is closely monitoring North Korea's movements," adding, "We maintain the capabilities and posture to respond overwhelmingly to any provocation."
