May 21 (UPI) -- Six Ukrainian troops were killed and at least 10 injured in a Russian missile strike as they practiced at a firing range in the northeastern Sumy region, Ukraine's National Guard said.
The commander of the unit was suspended following Tuesday's attack pending an investigation, with commanders and prosecutors to determine whether any crime had been committed after completion of the probe, the National Guard said on its social media account.
"Within the scope of the investigation, a legal assessment will be given to the actions of all persons who adopted the relevant decisions," said the National Guard, noting that its commanders had drawn up action-plans and signposted rules for dealing with the threat from air strikes, including banning too many personnel from gathering in a single location.
The National Guard did not give the location of the military facility, but the Sumy regional military administration said it was in Shostka, about 45 miles from the border with Russia's Kursk region.
