Roberto Escobar writes that his brother used airliners and two small remote-controlled submarines to move huge shipments of cocaine out of his Andean homeland. He says that to smuggle large quantities of coca paste -- the raw material for cocaine -- into Colombia from neighboring Peru, his brother built an airstrip alongside a clandestine drug laboratory in Colombia's eastern plains. To ensure that it would not be detected from the air, the pioneering cocaine merchant built an entire village on top of the airfield, Escobar writes. Buildings perched above the airstrip were constructed on wooden wheels and could be moved off it within three minutes whenever a drug-laden plane needed to take off or land, he says. Repeating allegations already denied by Peruvian officials, Escobar alleges in the book that Montesinos channeled $1 million in drug money from his brother into former President Alberto Fujimori's first election campaign a decade ago. When the allegations surfaced, Peru's justice minister dismissed them as "nonsense." Fujimori has since been fired as Peruvian president and is living in Japan. Escobar alleges that his brother had a close working relationship with Noriega, who was ousted in the aftermath of the U.S. invasion of Panama in 1989 and is serving a 40-year jail term in the United States for drug trafficking. "For Pablo and his friends Panama was a paradise without limits," Escobar claims, describing the country as a favourite playground of some Colombian mobsters.
