World Politics Watch have just published a two-part series on Gang Culture and Violence in Guatemala: Part One and Part Two. It makes for pretty chilling reading.

The series was written by Billy Briggs, the 2005 recipient of Amnesty International's Nations and Regions Award for his reporting on human rights issues.  His report is accompanied by photos by Angela Catlin.

Billy says on website about Guatemala:

"I recently visited Guatemala with photographer Angela Catlin to document the escalating violence and human rights abuses in one of the most violent nations in the world. There are more killings per day than there were during the dark days of a civil war that ended in 1996. The killing of women, the execution of selected individuals by elements within the police and military, gang and crime-related killings, 'social cleansing' by vigilante groups, and other acts of random violence have created a widespread sense of insecurity. Guatemala is a nation living in fear."

You can see his other articles on Guatemala on his website where he's written for The Sunday Herald, The Guardian and The Big Issue.
