By Gleb Stolyarov MOSCOW (Reuters) -Russian President Vladimir Putin fired his transport minister on Monday, in an unexpected move that comes at a time of significant challenges for the transport sector as the war in Ukraine drags on for a fourth year.

Russian President Vladimir Putin dismissed Transport Minister Roman Starovoit on July 7, following a series of high-profile disruptions to Russia's aviation and shipping sectors. The official decree was published on Russia's legal information portal.

Russia fired more than 100 drones at civilian areas of Ukraine overnight, authorities said Monday, as the Kremlin dismissed the country’s transport chief after a weekend of travel chaos when Russian airports grounded hundreds of flights due to the threat of Ukrainian drone attacks.
