South Korea scrambles jets as North Korea sends drones over border

Five North Korean drones crossed into South Korea on Monday and South Korea responded by scrambling jets and attack helicopters and opening fire to try to shoot down the North Korean aircraft, the South Korean military said. As part of its response, the South Korea military also sent surveillance aircraft into the North to photograph its military installations, a South Korean military official said.

"This is a clear act of provocation by the North violating our airspace," a South Korean official with the Joint Chiefs of Staff, Lee Seung-o, told a briefing. One of the five North Korean drones flew near the South Korean capital, Seoul, and the others flew near the west coast,

Lee said the South Korea military "operated assets to shoot down" the drones. He did not say if any drones had been shot down but the Yonhap news agency later said South Korea's military fired about 100 shots but failed to shoot any down. Lee said South Korea initially fired "warning shots" when it first detected the drones.

One of the drones was known to have returned to North Korea while South Korea lost track of the other four, Yonhap reported, citing the Joint Chiefs of Staff. North Korea has no channel for media queries from South Korea and its state media made no mention of any drones.

South Korean reconnaissance aircraft flew into the North to take photographs in action corresponding to the North Korean drone flights, Lee said, suggesting the North Korean drones were also meant for reconnaissance. South Korea tracked the drones crossing from North Korea over the so-called Military Demarcation Line between the two countries after detecting them in the skies of the western city of Gimpo at around 10:25 a.m. (0125 GMT), the military said earlier.

The drones are the first confirmed to have come from the isolated neighbour since 2017, when a North Korean drone believed to be on a spy mission crashed and was found on a mountain near the border. In 2014, a North Korean drone was discovered on a South Korean border island.

Those drones were considered crude aircraft mounted with cameras.

Lee said the North Korean drones on Monday were small, of about two metres, but he gave no further details including what equipment, if any, they were carrying. Relations between North Korea and U.S. ally South Korea have been poor for decades but have recently been growing even more tense after a new, conservative government took over in South Korea and North Korea presses on with its nuclear and missile programmes.

South Korea and U.S. forces have responded to a record number of North Korean missile tests this year with stepped up military exercises. North Korea sees such exercises as preparations for an invasion. Those have been met with more tests and drills from North Korea, including rare warplane sorties near the border.

South Korea's transport ministry said earlier that flights departing from its Incheon and Gimpo airports were suspended following a request from the military. The suspension began at 1:08 p.m. (0408 GMT) at Gimpo and at 1:22 p.m. at Incheon and lasted for about an hour before flight departures resumed at around 2:10 p.m., a ministry official told Reuters.

While scrambling to counter the drones, a South Korean KA-1 light attack aircraft crashed shortly after taking off from its base at Wonju in the country's east, a defence ministry official said. Its two pilots were able to escape before the crash and are in the hospital.
