Inside Navy's anti-piracy control room

Presidents and senior figures from more than 40 countries are meeting in London this week to address the problems of Somalia.

High on the agenda is maritime piracy which is costing the world economy an estimated $7bn a year. So what is being done to stop it?

The BBC's security correspondent Frank Gardner visited the UK Maritime Trade Operations (UKMTO) office in Dubai, the hub for distress calls from merchant vessels in trouble in the region.

The Royal Navy's Mark Ray talked him through what happens when the team receives a call.
