Taiwan is preparing its air-raid shelters as rising tension with China and Russia's invasion of Ukraine raise new fears about the possibility of a Chinese attack on the democratic island.

China considers Taiwan its territory and has increased military activity in the air and seas around it. Taiwan vows to defend itself and has made strengthening its defenses a priority, with regular military and civil defense drills.

The preparations include designating shelters where people can take cover if Chinese missiles start flying in, not in purpose-built bunkers but in underground spaces like basement car parks, the subway system and subterranean shopping centers.
