The UK government recently resupplied Ukraine with more Storm Shadow cruise missiles to enable Kyiv to continue its campaign of long-range strikes inside Russia, people familiar with the matter said.

Video from Sterlitamak in the Bashkortostan region, which is around 1,000km (620 miles) away from the border with Ukraine, captured an explosion at a petrochemical plant. Regional governor Radiy Khabirov later said Sterlitamak was attacked by two drones and “debris fell in an industrial zone”.
