A Bangladeshi labor activist who helped expose working conditions in the country’s garment industry has been brutally murdered. The body of 40-year-old Aminul Islam was found outside the city of Dhaka last week, but was initially buried because police could not identify him. Islam’s body showed signs of torture, with his hands and big toes having been smashed. Islam was arrested two years ago and tortured by police and intelligence services for protesting the garment industry’s low wages. Bangladesh is a major supplier of clothing for U.S. companies, including Wal-Mart and H&M, and has been gaining popularity among manufacturers as a lower-cost alternative to China. Dozens of workers have died in factory fires in Bangladesh in recent years.
