Nigeria becomes Africa's staging ground for the illegal pangolin trade with Asia

In a rubble-strewn storage lot in the sprawling Nigerian port city of Lagos, customs agents crack open a shipping container crammed with scales from pangolins, a shy mammal prized in Asia for its use in medicines.

The scales being stored with elephant tusks in the fetid container are part of a growing haul of pangolin cargos seized in Nigeria, a country that is now the main hub for gangs sending African pangolins to Asia, according to law enforcement officials, non-governmental organisations and wildlife experts.
