Russia and Ukraine exchanged 205 prisoners of war on Friday, hours after rescue workers ended their search of a destroyed block of flats in Kyiv in which 24 people were killed, including three girls. Most of the Ukrainian prisoners had been held since 2022, said President Zelensky. The swap was part of a short-lived ceasefire ending this week with the launch of massive Russian strikes across Ukraine, including a missile attack that reduced 18 flats to rubble. Among the victims was 12-year-old Lyubava Yakovleva, whose father was killed during the war. Meanwhile, Russian officials said four people, including a child, were killed when Ukrainian drones hit the city of Ryazan, south-east of Moscow.

How is Russia replenishing its military? What is a'coalition of the willing'? How China forgot promises and'debts' to Ukraine How are Europe, the US pulling apart on Ukraine? Russia's Putin hails war advances; Ukraine retakes parts of Donetsk John Psaropoulos is an independent journalist based in Athens and has been Al Jazeera's correspondent in Southeast Europe since 2012. Ukraine reclaimed 62sq km (24sq miles) of territory last month, its commander in chief revealed on Monday, contradicting Russian President Vladimir Putin's recent claim to be advancing "in all directions".

Kyiv's military administration warned residents of the Ukrainian capital to take shelter on Saturday night due to the takeoff of a Russian MiG-31K, the carrier of the Russian Kinzhal air-launched ballistic missile, in a post on Telegram. The International Atomic Energy Agency (IAEA) said that its team heard explosions and saw smoke coming from an "auxiliary facility" located 1,200 metres from the Russian-occupied Zaporizhzhia Nuclear Power Plant in Ukraine. The Russian-installed administration of the plant said that a civilian was killed by Ukrainian shelling. A fire that broke out near the plant was brought under control, the administrators added in a post on Telegram. An elderly man was killed inside a house that caught fire due to falling Ukrainian drone debris in Russia's Samara region, Governor Vyacheslav Fedorishchev posted on Telegram.

Ukrainian drone strikes have killed at least three people and wounded two others overnight in western Russia, regional governors said, as a fire broke out at an oil refinery in central Russia after it was hit. One woman was killed and two others wounded in an attack on an enterprise in Penza, the region's governor, Oleg Melnichenko, wrote on Telegram on Saturday. The second death of an elderly man happened inside a house that caught fire due to falling drone debris in the Samara region, Governor Vyacheslav Fedorishchev posted on Telegram. In the Rostov region, a guard at an industrial facility was killed after a drone attack and a fire in one of the site's buildings, acting Rostov Governor Yury Slyusar said. "The military repelled a massive air attack during the night," destroying drones over seven districts, Slyusar posted on Telegram.

Neither President Franklin Delano Roosevelt nor British Prime Minister Winston Churchill, nor any of their senior military or political advisors, saw the Japanese attacks of late 1941 coming. The forces of Imperial Japan achieved total surprise across the Pacific. The intelligence failures in the U.S. leading up to Pearl Harbor were catastrophic. So was Great Britain's general underestimation of the threat from Imperial Japan. The U.K.'s fortress outpost in the Pacific at Singapore was thought to be, if not impregnable, than as close to it as possible.

Russia's increased sense of vulnerability may be the most important result of a recent large-scale Ukrainian drone attack named Operation Spiderweb, experts tell Al Jazeera. The operation destroyed as much as a third of Russia's strategic bomber fleet on the tarmac of four airfields deep inside Russia on June 1. Days later, Russia started to build shelters for its bombers and relocate them. An open source intelligence (OSINT) researcher nicknamed Def Mon posted time-lapse satellite photographs on social media showing major excavations at the Kirovskoe airfield in annexed Crimea as well as in Sevastopol, Gvardiyskoye and Saki, where Russia was constructing shelters for military aircraft. They reported similar work at several airbases in Russia, including the Engels base, which was targeted in Ukraine's attacks on June 1.

Ukraine's Foreign Minister Andrii Sybiha said Russia had "responded" to Kyiv's audacious drone attack that destroyed Russian heavy bombers at airfields in Siberia last weekend by attacking civilians and civilian infrastructure in Ukraine. Russia's Ministry of Defence said its forces had carried out the strikes, which targeted military and military-related targets in response to what it called Ukrainian "terrorist acts" against Russia. Western military aviation experts told the Reuters news agency that Russia will take years to replace the nuclear-capable bomber planes that were hit in Ukrainian drone strikes on airfields in Siberia. Russia's National Guard said it killed a man as he tried to prepare a drone attack on a military site in Russia's Ryazan region, southeast of Moscow. Russian air defence units intercepted and destroyed 82 Ukrainian drones over Russian territory, including the Moscow region, Russia's Defence Ministry said early on Saturday.

Ukrainian drones struck multiple military airbases deep inside Russia on Sunday in a major operation a day before the neighbours held peace talks in Istanbul. The Russian Defence Ministry said Ukraine had launched drone strikes targeting Russian military airfields across five regions, causing several aircraft to catch fire. The attacks occurred in the Murmansk, Irkutsk, Ivanovo, Ryazan, and Amur regions. Air defences repelled the assaults in all but two regions – Murmansk and Irkutsk, the ministry said. "In the Murmansk and Irkutsk regions, the launch of FPV drones from an area in close proximity to airfields resulted in several aircraft catching fire," the Defence Ministry said.

Fox News senior White House correspondent Peter Doocy questions President Donald Trump about the Russia-Ukraine war. The brazen Ukrainian blitz of Russian warplanes Sunday was 18 months in the making and the Pentagon was kept in the dark until it was over, sources told Fox News. "Operation Spider's Web," a series of coordinated drone strikes penetrating deep into Russian territory, is believed to have taken out dozens of Russia's most powerful bomber jets and surveillance planes as they sat idle on five military airfields. The stunning operation was personally overseen by President Volodymyr Zelensky, Ukraine's security service (SBU) said. Ukraine used small FPV drones hidden inside wooden cabins mounted on trucks.
