There are concerns for the safety of Martín Barrios Hernández after he was seriously assaulted outside his home on 30 December 2003. The attack was the culmination of several verbal threats against him directly linked to his work as coordinator of the Comisión de Derechos Humanos y Laborales del Valle de Tehuacán, Human and Labour Rights Commission of the Tehuacán Valley, in Puebla State.
