A suspected North Korean drone had taken photographs of an advanced U.S. anti-missile battery in South Korea before it crashed on its way home, the South Korean military said on Tuesday.
The drone, mounted with a camera, was found last week in a forest near the border with North Korea. It was similar in size and shape to a North Korean drone found in 2014 on an island near the border.
“We confirmed that it took about 10 photos,” of the anti-missile system, known as the Terminal High Altitude Area Defense (THAAD), a South Korean Defense Ministry official said by telephone.
The drone was suspected to be from North Korea, the official added.
South Korea is hosting the anti-missile defense system in the Seongju region, about 250 km (155 miles) from the border with North Korea, to counter a growing missile threat from the North.
“We will come up with measures to deal with North Korean drones,” said an official at South Korea’s Office of the Joint Chiefs of Staff, who also declined to be identified as he is not authorized to speak to the media.
North Korean drones are known to have flown over South Korea several times.
North Korea has about 300 unmanned aerial vehicles of different types including one designed for reconnaissance as well as combat drones, the United Nations said in a report last year.
The North Korean drones recovered in South Korea were probably procured through front companies in China, with parts manufactured in China, the Czech Republic, Japan and the United States, it added.
The neighbors are technically at war after the 1950-53 Korean War ended in a truce and not a peace treaty.
South Korea and the United States agreed last year to deploy the THAAD unit in response to North Korea’s relentless development of its ballistic missiles, and nuclear weapons, in defiance of U.N. sanctions.
China strongly objects to the THAAD system saying its powerful radar can probe deep into its territory, undermining its security and upsetting a regional balance. China also says the system does nothing to deter North Korea.
