The Prague Post - Fresh confrontation between police, protesters in Bolivia

Demands for the business-friendly conservative to resign have persisted despite his promise to respond to the grievances of labor unions and Indigenous communities.

Many businesses had closed their doors, anticipating a repeat of the clashes that marked a similar demonstration on Monday.

"He should resign, damn it!" shouted the crowd of farmers, laborers, miners, transport workers and teachers who brought traffic to a halt on the streets of the Andean city.

Paz came to power six months ago, in the midst of the country's worst economic crisis since the 1980s, marked by acute shortages of fuel and foreign currency and runaway inflation.

"Six months in office and he hasn't been able to solve the basics... We have to choose between buying meat or buying milk," Melina Apaza, a 50-year-old demonstrator from the southern mining heartland of Oruro, told AFP.

Wearing helmets and ponchos, the protesters, many of whom waved rainbow-colored Indigenous flags, marched toward the city center to the din of firecrackers.

Under a dense cloud of tear gas, demonstrators hurled stones and sticks at riot police, who blocked them from reaching the square in front of government buildings.

- 'War of attrition' -

Paz has attempted to take the heat out of the protests by firing his unpopular labor minister and promising to give the miners, laborers and other groups in the street more of a say in shaping policy.

But his overtures appear to have fallen short of the mark.

Roads leading to La Paz continue to be blockaded by the protesters, causing shortages of food, medicine and fuel.

Trade unions began demonstrating in early May for wage increases, improved fuel supplies and economic stability.

But as the weeks passed, the demonstrations snowballed into a full-blown revolt, marked by calls for the resignation of the US-backed Paz.

His election -- part of a right-wing tide sweeping Latin America -- ended two decades of socialist rule launched by Indigenous coca farmer Evo Morales in the mid-2000s.

Paz's government accuses Morales, who attempted a comeback last year despite being wanted on charges of trafficking a minor, of fomenting the current unrest.

The government has "very little" wiggle room, political scientist Ana Lucia Velasco told AFP.

"Once demands escalate to the point of calling for a resignation, there's no backing down. It becomes more of a war of attrition," she said.
