Police Battle Paraguay Protesters June 22 By PEDRO SERVIN The Associated Press ASUNCION, Paraguay June 22 (AP) - Riot police fired tear gas and unleashed water cannons Thursday to disperse hundreds of workers on a strike called by labor unions opposed to a government privatization plan. At least 20 people were injured and dozens arrested, authorities said, as thousands of transport and other union workers launched the first of a two-day strike supported by three of the country's four largest labor groups. Most stores and schools in downtown Asuncion and in Ciudad del Este. Most public transportation ground to a halt. Union workers are incensed over a government plan to sell railroad, water, and telephone systems to private parties. Approved by the Senate in May, the plan is to be voted on by the lower house on June 29. Critics of the plan say putting the state-run businesses in private hands could leave the jobs of some 15,000 people at risk. Persio Duarte, a labor leader, threatened more strikes if the government didn't withdraw its plan. !In some way we're going to take revenge against the government," he told reporters. "Not with acts of violence, but with more strikes and protests that will disrupt this process of privatization." Government spokesman Jaime Bestard said the government would allow the strikes to continue, but would not revoke its proposed plan to privatize. "The right of the unions to strike will be respected," he told reporters. "But the project to reform the state will not be reversed. It's irreversible." A protracted economic crisis has brought widespread discontent with the government of President Luis Gonzalez Macchi, which has struggled to rejuvenate Paraguay's stagnant economy. With per capita income just above dlrs 1,600 a year, some 22 percent of Paraguay's 5.4 million people live in poverty. The unemployment rate hovers near 16 percent and 300,000 peasants in the countryside are clamoring for land. Many people depend on cash-strapped state enterprises for their livelihood.
