People watch a television screen showing a news broadcast with file footage of a North Korean missile test, at a railway station in Seoul, on November 2, 2022.
South Korea's Joint Chiefs of Staff said Saturday that the missiles flew around 130 kilometers (80 miles) toward the North's western sea.
North Korea this week launched dozens of missiles into the sea, including an intercontinental ballistic missile that triggered evacuation warnings in northern Japan, and flew warplanes inside its territory.
North Korea has described its military actions as an appropriate response to a combined U.S.-South Korea aerial drills, which it called a display of U.S. ``military confrontation hysteria.''
The United States flew two B-1B supersonic bombers on Saturday over South Korea on the final days of the joint drills, in a show of force meant to intimidate North Korea over its intensifying testing activity.
The United States will fly a supersonic bomber over ally South Korea as part of a massive combined aerial exercise involving hundreds of warplanes, in a show of force meant to intimidate North Korea over its barrage of ballistic missile tests this week that has escalated tensions in the region.
South Korea's Defense Ministry said at least one B-1B bomber will participate on the last day of a joint U.S.-South Korea air force exercise that wraps up Saturday. South Korean and U.S. military officials didn't immediately provide more details.
The ``Vigilant Storm'' exercise, which has involved about 240 warplanes, including advanced F-35 fighter jets from both countries, has triggered an angry reaction from North Korea.
The North this week launched dozens of missiles into the sea, including an intercontinental ballistic missile that triggered evacuation warnings in northern Japan, and flew its own warplanes inside its territory.
North Korea's Foreign Ministry late Friday described those military actions as an appropriate response to Vigilant Storm, which it called a display of U.S. ``military confrontation hysteria.'' It said North Korea will respond with the ``toughest counteraction'' to any attempts by ``hostile forces'' to infringe on its sovereignty or security interests.
B-1B flyovers had been a familiar show of force during past periods of tensions with North Korea. The planes last appeared in the region in 2017, during another provocative run in North Korean weapons demonstrations.
But the flyovers had been halted in recent years as the United States and South Korea halted their large-scale exercises to support the Trump administration's diplomatic efforts with North Korea and because of COVID-19.
The allies have resumed their large-scale training this year as North Korea dialed up its weapons testing to a record pace, exploiting a divide in the U.N. Security Council deepened over Russia's war on Ukraine as a window to accelerate arms development.
North Korea hates such displays of American military might at close range. The North has continued to describe the B-1B as a ``nuclear strategic bomber'' although the plane was switched to conventional weaponry in the mid-1990s.
Vigilant Storm had been initially scheduled to end Friday, but the allies decided to extend the training to Saturday in response to a series of North Korean ballistic launches on Thursday, including an ICBM that triggered evacuation alerts and halted trains in northern Japan.
Thursday's launches came after the North fired more than 20 missiles on Wednesday, the most it had launched in a single day. Those launches came after North Korean senior military official Pak Jong Chon issued a veiled threat of a nuclear conflict with the United States and South Korea over their joint drills, which the North says are rehearsals for a potential invasion.
South Korea also on Friday scrambled about 80 military aircraft after tracking about 180 flights by North Korean warplanes inside North Korean territory. The South's Joint Chiefs of Staff said the North Korean warplanes were detected in various areas inland and along the country's eastern and western coasts, but did not come particularly close to the Koreas' border.
The South Korean military spotted about 180 flight trails from 1 to 5 p.m., but it wasn't immediately clear how many North Korean planes were involved and whether some may have flown more than once.
In Friday's statement attributed to an unidentified spokesperson, North Korea's Foreign Ministry said the United States and South Korea had created a seriously ``unstable atmosphere'' in the region with their military exercises.
It accused the United States of mobilizing its allies in a campaign using sanctions and military threats to pressure North Korea to unilaterally disarm.
``The sustained provocation is bound to be followed by sustained counteraction,'' the statement said.
North Korea has launched dozens of ballistic missiles this year, including multiple ICBMs and an intermediate-range missile flown over Japan. South Korean officials say there are indications North Korea in coming weeks could detonate its first nuclear test device since 2017.
Experts say North Korea is attempting to force the United States to accept it as a nuclear power and seeks to negotiate economic and security concessions from a position of strength.
