Three heroic workers at the "Doomsday" site of the world's worst nuclear disaster risked their lives in a remarkable rescue mission - to save a stray dog.
A catastrophic malfunction at the power plant in Chernobyl, Russia in 1986, caused a mass evacuation of local towns around the plant, but some people are still on site, working on the clean-up operation.
More than 1,000 abandoned dogs have learned to survive in the woods around the exclusion zone, descendants of those left behind after the nuclear tragedy when residents were banned from taking their pets to safety.
Many have been befriended by workers who feed them.
However, last week, one of the adventurous animals managed to get up onto the snow -covered roof of the giant protective sarcophagus that covers Reactor 4.
