Drug submarine seized by police in Ecuador   A submarine built
by drug-traffickers has been found in Ecuador before its maiden
voyage.  The 31m (100 ft) vessel, capable of carrying 10-12
tonnes of cocaine, was discovered in a river near the border
with Colombia, the US Drug Enforcement Agency said.  US and
South American law enforcement officials have battled semi-
submersible craft for years that travel just below the surface
to avoid detection and take cocaine to Central America for
shipment to the US.  The captured craft is the first designed to
travel completely under water and was specially built for
smuggling drugs, authorities said.
