After oil mysteriously washed ashore on some 2,100 kilometers (1,300 miles) of Brazil’s coastline for two months, authorities on Friday identified a suspect: a Greek-flagged ship belonging to Delta Tankers Ltd. Brazil’s government has been striving to investigate the cause of the spill that has hit 286 beaches along the northeast coast and hurt fishing and tourism. The specific source of the oil has remained unclear since it began appearing in early September.
