Ukraine has hit back at Russia by attacking their airbase in Crimea - with three people injured by the explosions.
Among the three wounded was a 13-year-old boy with a cut wound on his forearm and a pensioner with a shrapnel wound - following an attack on Novofedorivka.
There were 15 explosions reported in 30 minutes in the annexed peninsula - which until now has avoided major assaults.
