That German ship with Iranian weapons

Don sent me this:  "After the whole world reported on the German Ship that IS carrying Iranian (or were it Russian?) weapons for Syria, it was all a farce.  No weapons were found at all and all papers were correct. The Atlantic Cruiser is continuing its trip.  Der Spiegel reports on who seemingly brought up the story first: “After Syrian opposition members had strongly warned the shipping company that there were weapons on board of the ship for the regime of the Syrian dictator Bashar al-Assad, the company had stopped the freighter and then immediately diverted it to Turkey. The opposition group, which called themselves "Syrian revolution Naval Forces" had threatened the shipping company and downright announced plans to sink the freighter at the planned entry into the Syrian port of Tartus.”"
