Taipei holds annual air raid drill to prepare for Chinese attack

Taipei came to a brief standstill on July 17 when air raid sirens forced people off the streets and into underground shelters in a rehearsal for a Chinese attack. The annual civilian drill is being held in cities across Taiwan this week, alongside military training, to prepare the self-governed archipelago for a potential Chinese invasion.
