Authorities in Argentina's capital, Buenos Aires, have launched a crackdown on employers who exploit Bolivian workers.

An estimated 15,000 Bolivians work in Argentina's garment industry - most of them in sweatshops where conditions are extremely poor. Many Bolivians who are working in Argentina illegally are exploited by the operators of clandestine factories that flout health and safety rules.

Officials say they will close any workshops where conditions are substandard.

The crackdown comes after six Bolivian workers died in a fire at a Buenos Aires textile factory last week. Four of the victims were children.
