A massive Russian drone and missile attack on Kyiv Saturday wounded at least 15 people, just as Russia and Ukraine were in the middle of a major prisoner swap.
Ukraine's air force said Russia launched 14 ballistic missiles and 250 attack drones overnight, adding that it downed six missiles and 245 drones.
The head of Kyiv's civil and military administration reported fires and fallen debris in several parts of the Ukrainian capital, after AFP journalists heard explosions overnight.
At least eight people were wounded in the attack, two of whom were hospitalised, according to the city's mayor Vitali Klitschko.
"The capital and the region are again under massive enemy attack. Air defence systems are continuously operating in Kyiv and its suburbs," he said on Telegram.
"With each such attack, the world becomes more certain that the cause of prolonging the war lies in Moscow," Ukrainian President Volodymyr Zelenskyy said on X.

Officials said five civilians were killed by Russian strikes in the Kharkiv and Donetsk regions.
The Russian military meanwhile said Ukraine had targeted it with 788 drones and missiles since Tuesday. Dozens of drones targeting Moscow have been shot down over the past week.
The attack on Kyiv comes hours after Russia and Ukraine completed the first stage of a prisoner exchange agreed at talks last week in Istanbul which, if completed, would be the biggest swap since the start of the conflict.
Both sides received 390 people in the first stage and are expected to exchange 1,000 each in total.
Russia has signalled it will send Ukraine its terms for a peace settlement after the swap, which is set to be staggered over three days — without saying what those terms would be.
The largest prisoner swap since war began
The two enemies have held regular prisoner swaps since Russia launched its 2022 offensive — but none have been on this scale.
An AFP reporter saw some of the formerly captive Ukrainian soldiers arrive at a hospital in the northern Chernigiv region, emaciated but smiling and waving to crowds waiting outside.
After they stepped off the bus, tearful relatives rushed to embrace the soldiers while others held pictures of their loved ones, hoping to find out if they had been seen in captivity.
Many of the soldiers were draped in bright yellow and blue Ukrainian flags.
"The first stage of the '1,000-for-1,000' exchange agreement has been carried out," Zelenskyy wrote on X.
"Today — 390 people. On Saturday and Sunday, we expect the exchange to continue."
Russia said it had received 270 Russian troops and 120 civilians, including some from parts of its Kursk region captured and held by Kyiv for months.
The two sides have not yet revealed the identities of those exchanged.
Diplomatic push yet to produce ceasefire
United States President Donald Trump earlier congratulated the two countries for the swap.
"This could lead to something big???" he wrote on his Truth Social platform.
Trump's efforts to broker a ceasefire in Europe's biggest conflict since World War Two have so far been unsuccessful, despite his pledge to rapidly end the fighting.
Diplomatic efforts to end the conflict have stepped up a gear in recent weeks, but the Kremlin has shown no sign it has walked back its maximalist demands for ending the fighting.
Moscow has defied European pressure for a full and unconditional truce in Ukraine, pressing on with its three-year offensive, which has left tens of thousands dead.
'It's impossible to describe'
One of the soldiers formerly held captive, 58-year-old Viktor Syvak, told AFP he was delighted to be back.
Captured in the Ukrainian port city of Mariupol, he had been held for 37 months and 12 days.
"It's very vivid. I didn't expect such a welcome. It's impossible to describe. I can't put it into words. It's very joyful," he said.
Several Ukrainians told AFP they were anxiously waiting to see if their relatives had been included in the swap.
"We have been looking for our son for two years," said Liudmyla Parkhomenko, a mother of a Ukrainian soldier who went missing during combat in the city of Bakhmut.
"Today I would like the Lord to send us good news ... We feel in our hearts that he's alive," she added.
Thousands of POWs still held by either side
After 39 months of fighting, thousands of prisoners of war (POWs) are held in both countries.
Russia is believed to have the larger share, with the number of Ukrainian captives held by Moscow estimated to be between 8,000 and 10,000.
With Kyiv not knowing the fate of thousands, each exchange brings surprises, a senior official told AFP.
"Almost every exchange includes people no one had knowledge about," he said.
"Sometimes they return people who were on the lists of missing persons or were considered dead."
