(Reuters) - Brazilian authorities identified a small oil leak off the shores of Rio de Janeiro on Saturday, the latest in a series of spills that has raised safety concerns over the development of some of the world's largest petroleum reserves.The latest oil leak comes days after a Brazilian prosecutor said he is widening a probe into offshore oil operations in the wake of a 3,000-barrel spill in an offshore field run by Chevron in November.
The new leak, which stretches for 1.2 miles (2 km), is estimated at 1,600 litters of oil (14 barrels) and remains far away from the coast, Rio de Janeiro's state Environmental Institute said in a statement. Officials were due to test the oil to try to determine its origin, but the leak is believed to have come from a ship in a sea route heavily transited by oil tankers. Read More
