Gaddafi's toxic Libyan legacy

There is growing concern over the legacy that the era of Muammar Gaddafi, the deposed Libya leader, is leaving behind, as tons of dangerous chemical waste has been found at sites around the country.

In a desolate part of southern Libya, about 800km from Tripoli, for example, about 10,000 drums of radioactive 'yellowcake', an essential ingredient in the uranium enrichment process, have been been found.
