Russian-Ukrainian conflict escalates with deadly drone attacks on Kyiv and retaliatory airstrikes.

Ukraine claims to have thwarted the largest overnight drone attack on Kyiv "since the start of the Russian invasion", with military authorities saying they had destroyed 52 of the 54 explosive drones launched by Moscow in the country, including "more than 40" over the capital. Ukraine's military intelligence has claimed, without offering evidence, that Russia is plotting a “large-scale provocation” at a nuclear power plant it occupies in the southeast of the country with the aim of disrupting a looming Ukrainian counteroffensive. Ukrainian President Volodymyr Zelenskyy on Saturday announced new sanctions against 220 companies and 51 individuals linked with Russia.
