The situation has not yet been resolved, and, in recent days, the pirates seized a Ukrainian ship known to be carrying heavy weapons bound for Sudan.
The US Navy surrounded the pirate-controlled Ukrainian ship, and the pirates had a shootout amongst themselves over what to do next.
Meanwhile Fox News also replayed the story of a mysterious cargo on the Iran Deyanat yesterday.
The Iran Deyanat is still being held, but I have not found any other sources (other than Andrew Mwangura and Hassan Osman) who claim the ship carries a dangerous cargo. Of course, apparently no one else besides the pirates has had access to the ship so far.
Various observers have pointed out (or claimed - I'm not sure how true the stories are) that the notion of China exporting iron ore to Rotterdam is odd and improbable, because China is overwhemingly an importer of iron ore, and the ship seems to be riding very high in the water to be heavily loaded with iron ore.
It's really uncertain what's going on here. It might be that the ship would have been ransomed by now if it weren't carrying something strange - or then again perhaps not. I spoke with a couple of real experts about this sort of thing, and they both expressed scepticism that there was an arms shipment involved, for a variety of reasons.
I have another one of those feelings (I've apparently been having a lot of them lately) that this situation may just fade away and we'll never know what was on the ship.
