Over the past 24 hours firefights occurred in several areas in Luhansk region, head of Luhansk regional military-civil administration Hennadiy Moskal said on Tuesday.

Ukrainian military personnel on the outskirts of Krymske and militants in Sokilnyke repeatedly exchanged fire using automatic weapon and grenade launchers, Moskal said on the administration's website.

"Later after 17:00 the positions of our servicemen near the bridge over the Siversky Donets River in Triokhizbenka were attacked with submachine guns and grenade launchers from the bank which is under the control of the so-called 'Luhansk People's Republic'. A similar exchange of fire occurred in Stanytsia Luhanska as well," he said.

Moskal went on to say that no civilians were killed or injured in the clashes, and that no infrastructure was damaged.
