6 Ukrainian soldiers killed in Russian strike on training exercise

A Russian missile strike on a training exercise in Ukraine's Sumy border region has killed six servicemen and wounded more than 10 others, says Ukraine's National Guard, reports BBC.

Russia's defence ministry had earlier released a video purporting to show an Iskander missile attack on a training camp, and state news agency Tass said up to 70 people had died.

The Sumy region has come under repeated bombardment, and Ukraine launched a months-long occupation of part of Russia's neighbouring Kursk region from there.

The Ukrainian military said the aim of the offensive had been to help create a buffer zone to protect Sumy, but some have complained of the scale of military losses._Agencies.
