Somali pirates hijack Iranian ship with chemical or radiological cargo

MS Iran Deyanat belonging to Iran state shipping company was hijacked a month ago, a common occurrence at the Somali coast though the ship of 45,000 tons is unusually large for pirates. Oddly, they asked for an unusually small ransom, just $200,000 which Iran allegedly paid.
Upon bringing the ship to Somali, the pirates tried opening its containers, but failed. They, however, received typical radiological skin burns and their hair fell out. The damage can be of chemical origin, too.
The ship, chartered by a German company, was departed China en route to, ostensibly, the port of Rotterdam. The choice of Iranian shipping for a legitimate cargo to Germany is suspicious.
Three decades ago, China supplied the uranium enriched on Soviet centrifuges to Egypt for its military nuclear program. This may be the case today, with Iran’s own centrifuges merely a smokescreen.
