Rise of modern-day pirates
By Sean Coughlan

Forget Johnny Depp and cutlasses. Pirates today carry AK-47s and use speed boats to plunder gas tankers and aid ships - with six attacks this week alone.

"Off Acheh, Malacca straits: Armed pirates in an unlit speedboat, blue hull, length about 10 metres. Approached a bulk carrier underway. They tried to board from stern. Raised alarm, crew mustered and activated fire hoses and directed search lights. Noticing crew alertness, pirates aborted boarding."

This isn't a scene from a movie, it's a real-life report of a pirate attack on Monday off the coast of Indonesia.

The pirates are not always foiled. The International Maritime Bureau's piracy monitoring centre has already recorded six attacks this week, including two which succeeded in robbing ships carrying relief to tsunami-affected areas.

"The big worry is that the attacks are getting much more violent," says Andrew Linington, of the maritime officers' union, Numast, which warns about the escalating problem.

"It's moved on from being maritime muggings, where half a dozen robbers would steal something and escape, to something much more organised with much greater use of weaponry."

"They're carrying AK-47s and in a number of cases using rocket-propelled grenades," says Mr Linington. He's amazed that the attacks haven't - yet - resulted in a major disaster.

"We've had cases where a fully-laden oil tanker has sailed down the Malacca Straits, the second busiest shipping route in the world, with no one at the controls because the crew have all been held at gunpoint. We've had gun battles being fought on board gas tankers.
