Kyiv: Social media videos showed Russian tanks driving through Obolon, an area just north of Kyiv's city centre on Friday.
Just in the past hour, Ukraine's defence ministry confirmed that Russian forces had infiltrated the residential district.
The videos appear to have been taken by locals in their homes. The BBC verified that the setting in these videos is Obolon.
Kyiv mayor Vitaly Klitschko said at least three people were injured when a rocket hit a multi-story apartment building in Ukraine's capital on Friday, starting a fire.
Ukrainian President Volodymyr Zelenskyy said that the Russian military's claim it is not targeting civilian areas is "a lie." He said that military and civilian areas in Ukraine are both being hit by Russian attacks.
Russia's invasion of Ukraine began early Thursday with a series of missile strikes, many on key government and military installations, quickly followed by a three-pronged ground assault. Ukrainian and U.S. officials said Russian forces were attacking from the east toward Kharkiv, Ukraine's second-largest city; from the southern region of Crimea, which Russia annexed in 2014; and from Belarus to the north.
