Satellite images show Iran has started operations at its heavy-water production plant in Arak — a strong sign that the nation has taken yet another step in its quest for nuclear-weapons development.

Heavy water is necessary for the operation of a nuclear reactor that can produce plutonium, Ynet News explains. And plutonium can be used to make a bomb.

British media has published the satellite images that were snapped earlier this month, Ynet said. The plant is located 150 miles outside Tehran. One of the images showed a cloud of steam coming from the plant — a near-sure sign that heavy water is being produced, according to Ynet.

Other images show that the plant is heavily secured. Numerous anti-aircraft missiles and artillery equipment can be seen at the site, Ynet said.
