KYIV, Feb 10 (Reuters) - Russia launched an overnight drone attack on Kyiv, sparking a fire at a non-residential building in one of the city's districts, the mayor of the Ukrainian capital said early on Monday.
"All emergency services are on site," Mayor Vitali Klitschko said in a post on the Telegram messaging app. "So far, there are no injuries reported."
Reuters witnesses heard a series of explosions in what sounded like air defence systems in operation.
