Anti-G8 demonstrators clash with police in Italy

VICENZA, Italy (Reuters) - Anti-G8 demonstrators clashed briefly with Italian police on Saturday in the first big protest ahead of next week's summit of the world's richest nations.

Police in riot gear fired teargas at protesters to prevent them from crossing a bridge and moving closer to a controversial U.S. military base in the north-eastern city of Vicenza.

A group of demonstrators, some of them wearing motorcycle helmets and with their faces covered, threw bottles, rocks and lit firecrackers they were pushed back by security forces.

Protesters were later allowed to continue their march, which broke up peacefully in the early evening. There were no reports of injuries.

Several thousand people attended the demonstration, launched against expansion plans that would make the U.S. base one of the biggest in Europe, and more generally against the July 8-10 G8 summit which Italy chairs.

"We are sick of the powerful governing without consulting the people," said Martina Vultaggio, 29, one of the protest organisers.

The leaders of the United States, Japan, Germany, France, Britain, Italy, Canada and Russia, together with those of major emerging economies, will hold talks in the central city of L'Aquila focussing on the state of the world economy, financial regulation, climate change, trade and development.

Anti-capitalist protesters have planned a series of demonstrations at different sites, starting with the one in Vicenza -- where locals oppose the doubling of the size of the U.S. base, home to 3,000 soldiers of the 173 Airborne Brigade.
