Two Ukrainian soldiers killed, 15 wounded and one reported missing, a presidential adviser Yuriy Biryukov reported 13 September on Facebook.
"Over 12 September, we have 2 dead, 15 wounded, 1 missing. I do not want to comment on the mêlée the subversive group, the mood is really foul. On balance: two dead, 5 wounded and 1 missing plus another 10 wounded all along the frontline: trapwires, frag wounds, you name it. A ghastly morning," Biryukov wrote.
Update. Defense Ministry spokesman on ATO Oleksandr Motuzyanik said three ATO troops were killed.
These were the largest daily losses since mid-July.
There were no dead or wounded on Sunday.
