The disturbances that broke out in Santiago and other cities as Chile marked the 40th anniversary of the military coup that toppled Socialist President Salvador Allende left scores of people hurt, 264 others under arrest, more than a dozen vehicles torched and about 200,000 households without electricity, Interior Minister Andres Chadwick said Wednesday.

A total of 42 members of the Carabineros militarized police force were wounded in clashes with demonstrators, Chadwick said.

Seven officers remain hospitalized, with six of them listed in serious condition with gunshot wounds and burns from acid, the interior minister said.

The level of violence this year was not as bad as on previous coup anniversaries, Chadwick told reporters.

Gen. Rodolfo Pacheco, commander of the Carabineros units in the western sector of Santiago, was among the officers hurt, the interior minister said.

Pacheco was hit in the head by a stone thrown by protesters in the working-class suburb of Cerro Navia and transported to the Carabineros Hospital.

Six buses and seven automobiles were torched by protesters armed with fire bombs, Chadwick said.

Four businesses were looted in Santiago and police prevented the lootings of 12 other stores, Chadwick said.

The disturbances spread across Huechuraba, San Bernardo, Estacion Central, Pudahuel, La Reina, Peñalolen and Lo Prado, all located around Santiago, on Wednesday night and into the early morning hours of Thursday.

Protesters put up barricades and attacked police, who responded with tear gas and water cannons.

About 200,000 households were left without electricity, electric utility Chilectra said.

Service was restored by 6:00 a.m. on Thursday, the electric utility said.

Allende took his own life as troops stormed the presidential palace on Sept. 11, 1973, and the coup was followed by 17 years of harsh military rule under Gen. Augusto Pinochet. EFE
