The Alazan rocket was a Cold War-era, 82mm Soviet rocket originally developed to distribute cloud seeding chemicals such as potassium or silver iodide.[1] Some were converted into improvised munitions and modified to carry explosive warheads. Others were retrofitted with a warhead, which, in one case, contained up to 400g of radioactive caesium-137 and strontium-90.[2] Both types were acquired by militants following the Soviet collapse.[2]
