A cyclist appears to have been hit by an explosive in a city in central Ukraine, as social media footage showed various images of destruction in the country after Russia began military action.

       Three videos which the PA news agency has geolocated to Kolomens’ka Street in Uman, a city in central Ukraine and just over 100 miles south of the capital Kyiv, show the person being thrown from their bike after a large, orange flash of light.

       CCTV footage shows the individual crawling from his bike before lying still. A second video taken on the ground depicts them in a pool of blood, with a small crater in the road nearby.

       In a third clip posted later in the morning on Facebook, the person has been removed from the street but windows on nearby cars can be seen smashed by the apparent blast.

       The videos are among many depicting destruction in Ukraine amid the Russian hostility.

       Some images depict flashes of light from explosions on the horizon, later followed by billowing smoke, with residents in Dnipro in the east of Ukraine confirming shelling had taken place there.

       Another video which PA geolocated to Chuhuiv, near Kharkiv in eastern Ukraine, shows an apartment building which has been severely damaged – with smoke pouring from it and all of its windows smashed.

       Security camera footage posted by Ukrainian authorities has shown Russian military vehicles crossing into the country from Crimea.

       In Kyiv, large queues of traffic have been filmed as residents flee the capital.
