Three technicians reportedly killed in submarine explosion in south Iran

Iranian state media are reporting three staff in the country's defense industries have been killed in an explosion in a submarine under construction in the country's south. A Saturday report by the Fardanews website said the three technicians were killed when batteries on the vessel exploded. The explosion took place at a ship-building factory about 37 kilometers (23 miles) west of the southern port of Bandar Abbas that overlooks the Strait of Hormuz. Since 1992, Iran has developed a homegrown defense industry that produces light and heavy weapons ranging from mortars and torpedoes to tanks and submarines.
