Two Ukrainian climbers, a man and a woman, fell to their deaths in Slovakia's High Tatra Mountains amid poor visibility in a snowstorm, rescuers said on Friday.

Slovakia's Mountain Rescue Service (HZS) said its rescuers "found two bodies" late Thursday after a group of 11 Ukrainian climbers reported two missing people near Lomnicky Peak, according to a statement.

"Both Ukrainian climbers, a man aged 67 and a woman aged 30, suffered fatal injuries," it said, adding that the rescue effort took place in difficult weather, with poor visibility due to falling snow and darkness.

Ukraine's mountain climbing federation said on Friday that the deaths occurred "on the descent from the (climbing) route as a result of a terrible accident", without going into detail. Kiev's "Vertical" mountaineering club identified the climbers as Volodymyr Mykhalko and Iryna Skrylyova on its Facebook page. Slovakia's HZS mountain rescue service said it had moved the bodies to a morgue in Novy Smokovec, a town in the High Tatra foothills in northern Slovakia, near the Polish border.
