Russian forces hit Ukraine 'with Iskander missile'

The Russian defence ministry did not provide the date of the strike but said the area around city of Konotop was targeted.

Ukrainian authorities in the region reported an Iskander missile strike on Konotop on Monday. 

The local administration said on Facebook that it had damaged flats in several multi-storey buildings and that there were no casualties.

Ukraine in recent days has been trying to drive Russian forces from the northern Sumy region, where border areas are gripped by heavy fighting. 

Ukrainian President Volodymyr Zelenskiy said on the weekend that Russia has amassed 53,000 troops in the region.
