On 18 September around 10am, Russian forces struck the eastern Ukrainian city of Kostiantynivka with a FAB-250 bomb with a UMPK guiding module, killing 5 civilians, the National Police of Ukraine reported. 

Kostiantynivka, in Donetsk Oblast, eastern Ukraine, is located near the front line and has been frequently targeted by Russian forces since the start of the full-scale invasion.

The FAB-250 is a Soviet-designed, 250-kilogram general-purpose bomb that Russia often modifies with glide kits such as the UMPK module to increase its range and accuracy.

The victims – three men and two women aged 62 to 74 – were killed in the street. Four apartment buildings were also damaged.

The Donetsk Regional Prosecutor’s Office has opened a pre-trial investigation into a potential war crime over the attack.
