Cocaine sub captured

Guatemala's Navy captured a makeshift submarine loaded with five tonnes of cocaine bound for the United States, the Guatemalan military said.

The Navy, working with the US Drug Enforcement Administration, stopped the 17m vessel off Guatemala's Pacific coast and arrested four Colombian men on board.

Such steel-and-fibreglass vessels run partly submerged in a bid to evade radar, but traffickers are working on more sophisticated designs.

Ecuadorean authorities recently found a nearly finished craft that would have been the first drug sub to travel completely underwater.
