Alright, alright already. I'll post about it. I must have been sent links to this story about a dozen times over the past few weeks: Hijacked Iranian Ship Was A Dirty Bomb Meant For Israel On Yom Kippur

The story goes that a group of Somali pirates that hijacked an Iranian ship got more than they bargained for when they got on board, opened some of the boxes, got gravely ill and died from whatever "sandy" substance was contained in the cargo. The remaining pirates kept the ship hostage before finally taking a ransom offer and allowing the ship to sail off: Somali Pirates Release Iranian 'Death' Ship

The story from the start sounded so extreme that I awaited more information before posting anything about it. I still haven't read anything that sounded authoritative to my ears on it. Even the A7 story quotes a skeptical expert:

I don't know about the strategic calculation involved -- actors in the region are notorious for miscalculating such things -- but I do find it curious that if there were such a ship, carrying such a cargo, that the US Navy would just stand idly by and let it sail off into the sunset. Don't you? So, I leave it to you, intrepid readers, to decide based on the scanty information, just what is going on here.
