"An oil pipeline spill that contaminated a river in the northern Mexican state of Nuevo Leon will take months to clean up, the country's top water authority said on Thursday.

The 24-inch Madero-Cadereyta pipeline, owned by national oil company Pemex, was ruptured when thieves attempted to tap into it, the company said on Sunday.

The pipeline feeds crude to Pemex's nearby Cadereyta refinery."
