Russian authorities say Ukraine has launched an "unprecedented attack" on and around St Petersburg, as the city hosts the final day of Russia's annual economic forum.

More than 140 drones were shot down over the surrounding Leningrad region, governor Aleksandr Drozdenko said, while the city's governor, Alexander Beglov, urged residents to remain indoors for the first time since the war began more than four years ago.
