Waves of Ukrainian drones batter the outskirts of city playing host to 'Russian Davos'

Ukraine has carried out a wave of drone strikes on cities across Russia, with some hitting targets in St Petersburg, more than 600 miles from the frontline. 

One of the largest oil terminals in North-western Russia went up in smoke after Ukrainian FP-1 drones hit it in the early hours of the morning.

The strikes also reportedly targeted Kronstadt, an island naval port near St Petersburg that is used by Russia's Baltic Fleet.

The attacks came just before international delegates arrived in the former capital for the St Petersburg International Economic Forum, often described as Vladimir Putin's version of Davos.

The deliberate timing saw international guests greeted by the sight of smoke rising over the city. 

Across the country, Russian officials claimed they intercepted 350 Ukrainian drones, including some over Moscow, and Novgorod in the west of the country.
