Tugboat sinks in northern Alabama and releases thousands of gallons of diesel into river

A sunken tugboat in northern Alabama released thousands of gallons of diesel fuel into the Tennessee River over the weekend, prompting evacuations of beaches and warnings to stay out of the water. 

The Florence, Alabama, police department said in a warning Sunday that 3,000 to 5,000 gallons of diesel were released into the river and fuel had begun to wash up on the beaches of McFarland Park.
