A picture taken with a mobile phote shows smoke rising near the Chernobyl nuclear power plant on June 4, 2018, after a wildfire has broken out at the exclusion zone around Chernobyl nuclear power plant. Ukrainian authorities on Tuesday said a wildfire had broken out in the exclusion zone around Chernobyl nuclear power station, the scene of the world's worst nuclear accident in 1986, but radiation remained within safe limits. "Radiation levels have not risen either inside the exclusion zone or in adjoining areas," the zone's administration said in a statement. / AFP PHOTO / Natalka LEVINA
