Hundreds of miners from a strike-paralyzed city in Bolivia's highlands have battled police in the capital of La Paz.

Miners threw rocks through windows of the Ministry of Government and then tossed small dynamite charges at police after officers used tear gas. A fire that broke out in pine trees at the adjacent German Embassy was quickly extinguished.

No injuries were reported in Wednesday's clashes as hundreds more protesters marched in the capital showing support for a civic committee that is seeking to negotiate an end to a 16-day-old general strike in Potosi, a provincial capital.

Potosi depends heavily on mining and its residents have been hit hard by a slump in mineral prices. They are demanding the central government put more money into public works projects.
