Another attempt to gather the materials for a dirty bomb. From the BBC, :
Authorities in Kyrgyzstan say they have arrested two men who were trying to sell a large quantity of plutonium on the black market.
The men were detained last week near the capital, Bishkek, but the news was not immediately released.
There has been growing concern that radioactive materials from former Soviet military or research sites could fall into the hands of extremists.
Plutonium can be used in atomic weapons or as reactor fuel.
The highly radioactive material could be used to make a dirty bomb – a non-nuclear explosive which scatters radioactive material packed inside it.
