Russian officials say Ukraine has carried out a series of deadly strikes on targets in south-west Russia over the past 24 hours
The emergency ministry says 14 people including two children have been killed and dozens of others injured in the city of Belgorod; the claim can't be independently verified
A Ukrainian security source has confirmed to the BBC that Kyiv fired 70 drones at Russian military targets - but blamed Russian air defences for fragments falling in Belgorod
The attack appears to be one of the deadliest strikes on Russia during the war so far
Moscow has repeatedly accused Ukraine of drone strikes on its territory, though Ukraine has not claimed responsibility for these
Today's attacks follow Russian strikes on Ukraine on Friday which killed 39 people, according to Ukrainian President Volodymyr Zelensky
Cities across Ukraine were attacked, including the capital Kyiv, Lviv in the west, Odesa and Zaporizhzhia in the south, and Dnipro and Kharkiv in the east
