A Russian drone hit the headquarters of the Ukrainian security services (SBU) in central Kiev. The attack occurred at a moment of high tension in the Ukrainian capital.
Volodymyr Zelensky reacted to the attack promising an "adequate and forceful" response against the Russian Federation.
The Russian threat could also jeopardize the visit of Donald Trump's envoys to Kiev, scheduled for this weekend. Washington recently sent a delegation to Ukraine to discuss a possible ceasefire agreement between Kiev and Moscow.
The visit of the American representatives comes in the context of diplomatic efforts to try to end the conflict between Russia and Ukraine.
