Unions call general strike in Argentina

One of Argentina's largest unions is staging a general strike in a challenge to President Cristina Fernandez. So far, the effect has been limited. There are a series of protest demonstrations, but business in and around the capital of Buenos Aires seems to be almost normal. Wednesday's strike was called by truckers' union leader Hugo Moyano, who also heads the General Labor Confederation. He's demanding steps that would effectively reduce taxes on low-income people, among other measures. Moyano was an ally of Fernandez's husband, former President Nestor Kirchner. But he has clashed with the current leader.
