More than 120 firefighters were trying to extinguish a blaze at an oil depot in the Russian city of Sochi that was sparked by a Ukrainian drone attack, regional Governor Veniamin Kondratyev said early on Sunday on the Telegram messaging app.

An overnight Russian drone and missile attack on Ukraine’s capital Kyiv has killed at least 18 people, including a six-year-old boy, as well as wounding 159 others, according to Ukrainian officials, prompting United States President Donald Trump to slam Moscow’s actions as “disgusting.”
