"Global preoccupation with rapid and unregulated urbanization and protracted urban violence os on the rise. Chronically violent cities - Abidjan, Baghdad, Ciudad Juarez Gaza, Guatemala, Kingston, Nablus, Grozny, Mogadishu and Rio de Janeiro - are all synonyms for a "new" kind of armed conflict with grave implications for humanitarian action and human welfare. These and other urban centers are experiencing a variation of warfare, often in densely populated slums and shantytowns." (Quoted from article)
