A large tarp covers 265 bales of marijuana aboard a panga March 17, 2014, before being seized by the U.S. Coast Guard with the assistance of Customs and Border Protection in the Pacific Ocean off the coast of southern California as part of Operation Martillo. The Coast Guard and Customs and Border Protection tracked and interdicted the panga more than 140 miles south of San Diego. Operation Martillo is a joint, interagency and multinational collaborative effort to deny transnational criminal organizations air and maritime access to the littoral regions of the Central American isthmus.
