Mexico deploys troops to curb drug violence

22 September 2012 Last updated at 09:48 BST

Around one thousand troops and federal police have been deployed to a suburb of Mexico City to combat worsening drug violence.

It is the first time during Mexico's drugs war that such a military operation has been deployed to part of the metropolitan area of Mexican capital.

The move follows a rise in fighting between rival drug gangs.
