The World : 17 Bombs Hurt 11 in Chile

Leftist guerrillas exploded 17 bombs in banks and other targets in Chile’s three largest cities, injuring 11 people, police said. Three banks, a school and a bakery were damaged in Santiago. The worst explosion occurred outside a bank in Concepcion, 327 miles south of Santiago, where the 11 people were hurt. Explosions were also reported in Valparaiso. Propaganda leaflets from the Manuel Rodriguez Front, a Communist guerrilla group, were found near the site of one of the bombings. The front has claimed responsibility for hundreds of bombings since it began a campaign of violence against the military government two years ago.
