SANTIAGO, Chile - Chilean officials are investigating the death of hundreds of penguins, pelicans and other animals that are washing up on the county's shores.

Authorities say they suspect that fishermen using explosives may have killed the animals found at the town of Punta de Choros on Chile's north-central coast.

Chile's National Fishing Service and the Navy are inspecting vessels around the area.

Environmental group Oceana is urging officials to find and punish those responsible for the deaths.

Chile has more than 2,500 miles (4,000 kilometres) of coastline and fishing is among its top industries.
