SESENA NUEVO, SPAIN - MAY 13: A helicopter drops water onto burning tyres at an illegal dump on May 13, 2016 in Sesena Nuevo, Spain. The dump, which stored over 75.000 tonnes of used rubber tyres was declared illegal in 2003 but both the Regional government of Madrid and Castilla La Mancha were unable to come to an agreement as to who would pay for the estimated 4 million euro clean-up and removal of the dump.
