North Korea regularly conducts short-range missile tests. Analysts say the recent launches appear to be weapons tests or an attempt to get U.S. and South Korean attention amid tentative signs of diplomacy after soaring tensions that followed U.N. sanctions aimed at a North Korean nuclear test in February.
The two projectiles fired by North Korea on Monday had similar trajectories as four previous launches over the past two days, according to officials at Seoul's Defense Ministry and Joint Chiefs of Staff. Officials were analyzing whether the projectiles were missiles or rockets fired from a large-caliber gun North Korea may be developing, the officials said on condition of anonymity citing department rules.
Defense Ministry spokesman Kim Min-seok told reporters earlier Monday that South Korea is taking seriously whatever weapons North Korea develops because it could attack the South. He said artillery guns with a larger caliber will likely have more destructive power.
South Korea urged North Korea to behave responsibly, while the U.S. said threats or provocations would only further deepen the North's international isolation.
North Korea's Committee for the Peaceful Reunification of Korea on Monday called South Korean and U.S. criticism an "intolerable challenge" that is deepening tension. It said it conducted "rocket launching tests" on Saturday and Sunday as part of drills to bolster deterrence against what it calls U.S. and South Korean plots to launch nuclear strikes against North Korea. It didn't comment on Monday's firing.
North Korea has a variety of missiles but Seoul and Washington don't believe the country has mastered the technology needed to make nuclear warheads small and light enough to be placed on a missile capable of reaching the U.S.
The Korean Peninsula officially remains in a state of war because the 1950-53 Korean War ended with an armistice, not a peace treaty.
