Amnesty International Urgent Actions:

Mariela Mendoza, eyewitness to her brothers' murders - just three of more than 100 others allegedly killed between 1999 and 2002 by an ''extermination group'' that operated inside the Portuguesa state police force - has just narrowly escaped an attempt on her life. Urge the Venezuelan government to investigate the recent murder attempt on Mariela Mendoza and to guarantee her safety.
