Ukraine's president plans to use the Nato meeting in Turkey to urge Kyiv's allies to deliver the air defence systems it urgently needs to protect it from escalating Russian attacks. Volodymyr Zelensky's call for help rings with extra intensity after Russian missiles rained down on the Ukrainian capital twice in less than a week, crashing into blocks of flats and killing more than 50 civilians. The summit in Ankara will also be a chance for Zelensky to hold a crucial meeting with Donald Trump and press home his case that Russia's brutal attacks are a show of weakness, not strength, and that Vladimir Putin should be pressured into talks towards a dignified peace. The latest strikes on Ukraine come as it has been stepping up its own long-range drone attacks against Russia, hitting oil refineries and military targets there and causing significant fuel shortages and power cuts.

Russia has threatened to launch a fresh wave of systematic strikes against Kyiv, days after carrying out one of its largest attacks on the Ukrainian capital since the start of the war. The new strikes will target decision-making centres and command posts, alongside drone manufacturing facilities in the city, Russia's foreign ministry said in a statement. Moscow has called for foreign nationals and diplomats to leave Kyiv as soon as possible and warned citizens to stay away from administrative and military buildings. Large-scale Russian strikes on Saturday night killed four and injured about 100 people in Kyiv and other areas, Ukrainian President Volodymyr Zelensky said. Moscow said that barrage and threatened further strikes were in response to what it claims was a deliberate Ukrainian attack on a student dormitory in the town of Starobilsk on Friday, in which Russian officials said 21 people were killed.

Meanwhile, Ukraine carried out some of its longest-distance drone strikes deep inside Russian territory.
