All was quiet in the anti-terrorist operation zone in eastern Ukraine in the past 24 hours, yet one Ukrainian serviceman was injured in a demining operation, Ukrainian Presidential Administration spokesman for the army operation Andriy Lysenko has said.

"No provocations were observed along the contact line over the past day, and hostile drones were not seen flying either. One Ukrainian serviceman was injured in a grenade explosion. That happened near Maryinka when the serviceman was doing demining works," Lysenko said at a press briefing in Kyiv on Wednesday.
