Russia killed at least four people, including an infant, overnight in its worst airstrike of the war in Ukraine. The strikes ignited Ukraine’s Cabinet of Ministers building in central Kyiv.

Ukrainian President Volodymyr Zelenskyy said the drone and missile barrage struck across the north, south and east of the country, as well as other regions.

In a post on X, Zelenskyy called for broad response from allies including the U.S., seeking sanctions and strong actions against Russia. "Clearly Russia is trying to inflict pain on Ukraine, with even more brazen attacks," he said. "This is a clear sign that Putin is testing the world - whether they will accept to tolerate this."

Elsewhere in Kyiv, residential apartments were damaged. Dozens of residents wrapped in blankets gathered on the streets to survey the damage to their homes as rescue workers fought to extinguish the flames.

According to the Institute of the Study of War, Russian forces launched more than 823 projectiles in its strike Sept. 7, including Iranian Shahed-type and decoy drones. In addition, Russian forces launched four Iskander-M/KN-23 ballistic missiles from Crimea and nine Iskander-K cruise missiles from Kursk Oblast, according to the Ukrainian Air Force.
