Russia hits Ukraine's Security Service headquarter in central Kyiv

Ukrainian President Volodymyr Zelenskyy says

Russian drone strikes hit the headquarters of Ukraine's

Security Service in central Kyiv.

Ukraine officials say the move is a major escalation and demand a resolute response.

This in a string of attacks by the Russians over the past several

days that saw destruction to residential areas as well as

major warehouse, including one housing a significant supply

of pharmaceuticals.

The hit also marks an increasingly bold move by the Russians

to launch daylight attacks on its opponent.

Five people are said to be injured in the incident.
