President Nicolas Sarkozy on Friday pledged more police and major investments for neglected housing projects nationwide in a plan for neighborhoods that exploded in riots in 2005 and late last year. Sarkozy unveiled the much-awaited, far-reaching plan for reinvigorating isolated suburban housing projects and better integrating their youths. The conservative president stressed security measures and declared a «war without mercy» against drug traffickers in such neighborhoods, according to a report of the Associated Press.
