A ship is missing: pirates, terrorists?

It could be a thriller or a spy novel but it is a real thing. In the 21st century . What was though at the beginning as a piracy act, in itself outlandish enough due to the European location, is getting new and much more sinister interpretations. It seems that the vessel was loaded at the Finnish port of Jacobstad on July 23. The followthe “Arctic Sea”, a Maltese-registered ship carrying a $1.3-million cargo of timber from Finland, was supposed to have docked on August 4 in the Algerian port of Bejaiaing day the ship was supposedly boarded by a group of armed men claiming to be Swedish police searching for drugs in the Baltic Sea. The crew said the sip was searched while they were tied for hours but the Swedish authorities have denied any knowledge of the operation. What did happen during those hours and who boarded the ship? Nobody seems to know. Everybody is trying to come out with different scenarios among them, and one quite credible is the one from Mikhail Voitenko, editor of Russia’s Sovfracht maritime bulletin. He said the “Artic Sea” might have been loaded with an unknown cargo while it was being reoaired for two weeks in a sipyard in Kalinningrad. Mr Voitenko added: “The only sensible answer is that the vessel was loaded secretly with something we don’t know anything about. I’m sure it cannot be drugs or illegal criminal cargo. I think it is something much more expensive and dangerous.”
What are we talking about here? Arms? Nuclear weapons? Whatever it has happened to the ship, it has finally made the Russian government interested enough to have President Dmitry Medvedev ordering the Russian navy to join the hunt for it. Warships and nuclear submarines have have been told to “take all necessary measures to find and free” the ship and its 15-man Russian crew.
One is almost hoping the vessel was seized by pirates instead of we many of us fear: terrorists.
