"The armed forces of the Russian Federation and its mercenaries violated the ceasefire once on July 23. The enemy opened fire on our defenders from an automatic grenade launcher and rifles," the press center of Ukraine's Joint Forces Operation (JFO) Headquarters said in an update posted on Facebook as of 07:00 Kyiv time on July 24, 2019.

Under attack came Ukrainian positions near the village of Luhanske.

According to Ukrainian intelligence reports, three enemy troops were killed and another one was wounded as a result of stepping on an explosive device.

Since Wednesday midnight, enemy troops have not violated an indefinite ban on the use of weapons.

"The Joint Forces reliably control the enemy along the contact line, while adhering to the ceasefire," reads the report.
