Watch: Russia launches large missile attack on Kyiv
Russia has launched a large missile attack on Kyiv, Ukrainian officials say.
Video shows burning debris falling from the sky and smoke billowing in the background, as people took shelter in a subway station.
Several explosions were also heard as Ukraine's anti-missile defence systems were activated.
It is the largest Russian attack on the capital in weeks, and follows a vow from Moscow for revenge over recent attacks by Ukraine on its border regions.
