Cities have become the new battleground of our increasingly urban world. From the slums of the global South to the wealthy financial centres of the West, Cities Under Siege traces the spread of political violence through the sites, spaces, infrastructure and symbols of the world’s rapidly expanding metropolitan areas. This book is a new original study of the subtle interpenetration of global geopolitics and the micro–politics of cities and neighbourhoods from the ground-breaking expert of the rapidly rising, crucial, field of urban geopolitics – acts of war against cities and their inhabitants.
