Russia launched a large drone attack on Kyiv overnight, with Volodymyr Zelenskyy warning the attack shows his capital needs better air defences.
Ukraine's air defence units shot down 50 of 73 Russian drones launched, with no immediate reports of damage or injuries as a result of the attacks.
Russia has used more than 800 guided aerial bombs and around 460 attack drones in the past week.
Warning that Ukraine needs to improve its air defences, Ukrainian President Volodymyr Zelenskyy said: "An air alert has been sounded almost daily across Ukraine this week".
"Ukraine is not a testing ground for weapons. Ukraine is a sovereign and independent state.
"But Russia still continues its efforts to kill our people, spread fear and panic, and weaken us."
Russia did not comment on the attack.
It comes as Russian media reported that Colonel General Gennady Anashkin, the commander of the country's southern military district, had been removed from his role over allegedly providing misleading reports about his troops' progress.
While Russian forces have advanced at the fastest rate in Ukraine since the start of the invasion, forces have been much slower around Siversk and the eastern region of Donetsk.
