Russia's hybrid military forces mounted 13 attacks on Ukrainian army positions in Donbas on Saturday, using weapons banned by the Minsk accords in two instances.

The situation in the area of the Joint Forces Operation remained controlled, the press center of Ukraine's Joint Forces Operation (JFO) said in an update on Facebook as of 18:00 Kyiv time on June 16, 2018.

Using mortars and cannons of infantry fighting vehicles, the militants tried to improve their tactical position near the town of Zolote in the Luhansk sector.

However, the JFO units opened return fire suppressing the occupiers' attempts to move towards their positions.

The militants also targeted the area on the outskirts of Avdiyivka and Zaitseve in the Donetsk sector, the report said.

In the Mariupol direction, the invaders fired grenade launchers and small arms at the villages of Vodiane and Shyrokyne.

The Ukrainian units fired back if needed to deter the enemy's firing activity, but without violating the Minsk accords.

There have been no casualties among Ukrainian troops for the current day. The enemy's losses are being clarified.

As UNIAN reported earlier, Russian-backed militants violated the ceasefire 36 times in the past day, using heavy weapons in nine instances.
