South Korea held a nationwide civil defense drill for the first time in six years on Wednesday, as a part of bolstered responses to North Korea¡¯s repeated missile launches.

The drill, based on a North Korean air raid scenario and lasting 20 minutes from 2 p.m., required South Korea¡¯s 51 million residents to practice evacuating to shelters or underground spaces such as train stations.

While government officials took part in the drill, posts to social media appeared to show that a number of residents, businesses, shops and restaurants went about business as usual, largely ignoring the drill.
