Chile troops, police attack post-quake looting

CONCEPCION, Chile (AP) — Rescuers found signs of life in a quake-toppled building on Monday as the world offered aid to victims of a catastrophe that killed more than 700 people. Troops and police cracking down on looters arrested dozens of people for violating a curfew. “We are confronting an emergency without parallel in Chile’s history,” Bachelet declared Sunday, a day after the magnitude-8.8 quake — one of the biggest in centuries — killed at least 708 people and destroyed or badly damaged 500,000 homes.
