The projectiles were fired from North Korea's Hamhung area around 6 p.m., South Korea's Joint Chiefs of Staff said in a statement on Sunday. The projectiles flew about 110 kilometers (about 68.3 miles) at an altitude of 25 kilometers (15.5 miles), with a maximum speed of Mach 4.0 or lower, said the statement.
On Sunday, North Korean state media KCNA reported Kim had observed the test firing of a "new-type tactical guided weapon," which was "carried out successfully." KCNA claimed the new weapon boosted the country's "frontline long-range artillery units," and increased efficiency "in the operation of tactical nukes of (North Korea) and diversification of their firepower missions."
