At least three people were killed and more than 20 injured in a large Russian drone-and-missile attack on Ukraine's eastern city of Kharkiv. Kharkiv's mayor called the overnight strikes on Ukraine's second city the most "powerful attack" on it of the war so far.
"Kharkiv is currently experiencing the most powerful attack since the start of the full-scale war," Kharkiv's mayor, Ihor Terekhov, said on the Telegram messenger app early on Saturday.
He said the attack damaged apartment buildings and homes.
It comes a day after Russian strikes hit six Ukrainian territories, killing at least six people and injuring about 80 others.
Ukraine says Russia launched more than 200 drones overnight
The Ukrainian military said Russia launched 206 drones, 2 ballistic and seven other missiles against Ukraine overnight.
It said its air defense units shot down 87 drones while electronic measures jammed another 80 drones.
The intensity of the Russian attacks on Ukraine over the past week has further dampened hopes that the warring sides could reach a ceasefire agreement.
Ukraine has offered a 30-day unconditional ceasefire as an attempt to end the war but Russia has continuously rejected such overtures.
On Friday Ukrainian President Volodymyr Zelenskyy on Friday called for allies to increase pressure on Russia to end its war of aggression.
Earlier in the week US President Donald Trump said his Russian counterpart, Vladimir Putin, told him Moscow would respond to Ukraine's attack last weekend on Russian military airfields.
Russian strikes hit multiple cities as Ukraine targets Moscow
Besides the large Russian aerial assault on the Ukrainian city of Kharkiv, there were also strikes on Donetsk, Dnipropetrovsk, Odesa, and the city of Ternopil, Ukrainian Foreign Minister Andrii Sybiha said in a post on social media.
"To put an end to Russia's killing and destruction, more pressure on Moscow is required, as are more steps to strengthen Ukraine," he said.
Russia, meanwhile, said it downed 36 Ukrainian drones on Saturday.
At least two people were injured in the Moscow region as a result of the Ukrainian drone attack, Governor Andrei Vorobyov said.
Russia's aviation watchdog said the Domodedovo, Sheremetyevo, and Zhukovsky airports in the Moscow region had temporarily suspended operations to ensure flight safety but that flights had resumed.

Russia accuses Ukraine of 'postponing' POW swap
Russia accused Ukraine of postponing a large-scale prisoner swap on Saturday.
"The Ukrainian side has unexpectedly postponed for an indefinite period, both the acceptance of the bodies and the exchange of prisoners of war," Russia's top negotiator Vladimir Medinsky said on social media.
Ukrainian and Russian negotiators agreed to exchange prisoners, focusing on swapping severely wounded individuals and repatriation of bodies.
They met on Monday in the Turkish city of Istanbul for their second round of direct peace talks since 2022, but the two sides are still far apart on how to end the war.
There was no immediate comment from Ukraine.
Previous prisoner-of-war exchanges between the two sides have generally proceeded smoothly.
