The message came as the Russians entered the Obolon district of Kyiv, the capital.
"We ask citizens to inform about the movement of equipment!" said the message posted by the Defense Ministry of Ukraine.

The nation’s airborne assault troops targeted the bridge, which crosses the Teteriv River at Ivankiv, helping ground forces stop a Russian tank convoy, Ukraine’s Defense Ministry said, according to Newsweek.
