It was reported by pro-Russian source Rybar that Ukraine conducted a strike on occupied Cape Tarkhankut in Crimea, Ukraine on the night of the 27th of April going into the early morning of the 28th of April.
There is no damage assessment at this time, and as it has been a number of days it is likely that no successful attack occured.
Additionally, over night on the 29th-30th of April explosions were heard in Crimea. Rumours suggest that a Russian helicopter squadron at an air base in Dzhankoi may have been the target.
