**Deck**: A Russian strike hit Ukraine’s security service building in central Kyiv, injuring several people and damaging nearby structures, Ukrainian officials say. President Volodymyr Zelensky says acting security chief Oleksandr Poklad has reported on preparations for retaliatory actions, with the ‘geography’ of Ukraine’s response already chosen.

A Russian attack on central Kyiv has damaged Ukraine’s main security service building and prompted President Volodymyr Zelensky to signal a prepared response.

Ukrainian authorities say the country’s security service headquarters in the heart of the capital was struck on 4 September. Kyiv Mayor Vitali Klitschko reported that the number of people injured in the strike rose to nine.

Nearby, the consistory building of Saint Sophia Cathedral also suffered damage from a separate reported strike. According to Ukrainian public media, windows were blown out and a glass entrance structure was destroyed, while the cathedral itself was not harmed.

Video published by Ukrainian channels showed the central security building on fire. Earlier updates from officials noted that the number of injured in Kyiv increased from five to seven before reaching nine.

Zelensky later said that acting Security Service chief Oleksandr Poklad had reported on preparations for Ukrainian retaliatory actions in response to Russian strikes. In remarks reported in English and Ukrainian, Zelensky stated that the geography of the response had been determined and that the timing would be chosen to ensure results.

Ukraine’s Security Service has also said that Russia will receive a painful response, referring to more special operations, exposed agent networks and destroyed enemies in connection with the day’s attacks.

The key developments to watch now are where and how Ukraine chooses to carry out the promised retaliatory actions, whether Russia continues to target central government and cultural buildings in Kyiv, and how these exchanges influence further security assistance and air defense priorities for the capital.
