In Ukraine, an ammonia leak early today at a chemical plant in the eastern city of Sumy has contaminated an area with a radius of more than 2.5 kilometers.

Zhyuvytskyy however said that there is no threat now to Summy since the wind does not blow on the city. He said the nearby village of Novoselytsya, about 1.5 kilometers southeast of Sumy, is under threat.  Emergency crews were working to contain the leak.</span><br />
