Following days of protests and strikes, Colombia's largest port city of Buenaventura exploded into violence May 19 as police opened fire on demonstrators, leaving one dead and many wounded. Marches have since continued in the city in defiance of a curfew, and scores have been detained. The protests are part of a regional campaign over harsh conditions on Colombia's Pacific coast. Buenaventura is one of South America's most important ports, yet half the city's 400,000 residents have no access to potable water. The protests began in Chocó department, up the coast from Buenaventura, under the slogan "Down with Colombia's corrupt oligarchy!" Strike leaders charge that millions of dollars in infrastructure investment for the region have disappeared.
