LVIV, Ukraine (Reuters) – The mayor of Kyiv said on Monday a new, longer curfew was being introduced in the Ukrainian capital because the authorities expect further shelling by Russian forces. Mayor Vitali Klitschko had earlier on Monday announced a “reinforced curfew” in the Ukrainian capital from 8.00 p.m. (1800 GMT) until 7 a.m. on Wednesday.
