An oil slick on the Moskva River in Moscow caught fire Wednesday afternoon, sending a plume of heavy black smoke skyward in the southern part of the city.
Alarmed Muscovites shared photos and video of the plume on social media, which can be seen below.
Two adults and one 9-year-old child were injured in the fire and taken to a local hospital, according to Russia Today. Firefighters extinguished the blaze, which stretched about 300 feet down the river, in 15 minutes.
Moscow police told TASS that a patch of grass on the riverbank caught fire, which in turn ignited the river.
