Air raid drills have been held across South Korea on the scenario of a contingency on the Korean Peninsula.
Central and local government officials and school staff on Tuesday took part in the first nationwide civil drills in six years.
At the Seoul city office, public officials evacuated to the underground hall, their designated shelter, when the air raid siren sounded. They heard a lecture on life-saving techniques and performed CPR on a dummy.
A man in his 20s said it's been a long time since the last drill, and it's good to learn emergency procedures firsthand.
The administration of President Yoon Suk-yeol notes that North Korea's repeated missile launches have heightened security concerns.
It plans to expand the scale of the drills and have more members of the general public join them to strengthen the country's capability to respond to a contingency.
