Taipei will come to a standstill Thursday as Taiwan conducts one of its largest civil defence drills amid growing tensions with China. Air raid sirens will sound across the city, with residents required to shelter indoors and traffic and businesses temporarily halted. The exercise includes mass evacuations and emergency response rehearsals, according to BBC.

This drill is part of Taiwan’s expanded Han Kuang war games, involving over 22,000 troops practicing defence on land, sea, and air, as well as urban warfare and countering misinformation.

Despite fears of a Chinese invasion, many Taiwanese remain doubtful it will happen soon but recognize the importance of preparedness. Taiwan continues to strengthen its military and civil defence capabilities in response to ongoing threats, BBC reported.
