Russia overnight hit Ukraine with the biggest missile and drone attack of the war, launching a record number of drones at Kyiv.

Russia pummelled Kyiv with drones in an all-night attack, injuring at least 14 people, damaging railway infrastructure and setting buildings and cars on fire throughout the city, authorities in the Ukrainian capital said early on Friday.

Waves of drone and missile attacks targeted Kyiv overnight into Friday in the largest aerial attack since Russia's invasion of Ukraine began more than three years ago, injuring 23 people and inflicting severe damage across multiple districts of the capital in a seven-hour onslaught.
