A 200-kilometer oil spill along Mexico's Gulf Coast has been identified as the origin of the spill, not from natural seepage but from a private oil tanker off the coast of Tabasco. The spill has contaminated a 230-km stretch of beaches in Veracruz and Tabascon, with environmentalists warning that it could affect the beaches for up to two months. The cause of the leak has not yet been determined. Pemex has denied responsibility for the spill but joined the cleanup effort to show support for the environment and coastal communities. The Navy responded to complaints from local communities that insufficient action was being taken.
