Thousands of Argentine farmers blocked highways on May 8 to protest increased taxes on soy, a major export crop. The farmers had struck in March, halting shipments of grain throughout the country and presenting the center-left government of President Cristina Fernandez de Kirchner with its biggest challenge since she took office in December.
