Ukraine’s capital came under a large-scale combined drone and missile attack late Friday with explosions and machine gun fire heard throughout the city.
Many Kyiv residents were taking shelter in underground subway stations.
The nighttime Russian attack that stretched into early Saturday came hours after Russia and Ukraine began a major prisoner exchange, swapping hundreds of soldiers and civilians in the first phase of an exchange that was agreed on by the two sides at a meeting in Istanbul last week.

The agreement was a moment of cooperation in otherwise failed efforts to reach a ceasefire in the 3-year-old war.
The debris of intercepted missiles and drones fell in at least 4 city districts of the capital, acting head of Kyiv military administration, Tymur Tkachenko, wrote on Telegram.
According to Tkachenko, six people required medical care after the attack, two fires sparked at Solomianskyi district of Kyiv.
Prior to the attack, city mayor Vitalii Klitschko warned Kyiv residents of more than 20 Russian strike drones heading towards Kyiv.

The prisoners swap Friday was the first phase of a complicated swap involving prisoners and civilians.
President Volodymyr Zelensky said the first phase brought home 390 Ukrainians, with further releases expected over the weekend that will make it the largest swap of the war.
Russia’s Defense Ministry said it received the same number from Ukraine.
The exchange, which would be the latest of dozens of swaps since the war began and the biggest involving Ukrainian civilians at one time, didn’t herald any halt in fighting.
Battles also continued along the roughly 1,000-kilometer (620-mile) front line, where tens of thousands of soldiers have been killed, and neither country has relented in its deep strikes.
