One Russian fighter has been killed, another one has been injured in an explosion of a militant-planted landmine near the Svitlodarska Duha bulge in Donbas, eastern Ukraine.

The two fighters are from the so-called 7th separate motorized rifle brigade of illegal armed formations deployed in the occupied areas, the press center of the Anti-Terrorist Operation (ATO) Headquarters said.

The incident happened on the same day, it said.

The Headquarters of Ukraine's military operations did not rule out that pro-Russian media outlets might try to blame the ATO forces for violating the Minsk agreements and would probably impute these casualties to the Ukrainian army.

The ATO HQ said it was checking whether the two Russians belonged to the regular troops of the Russian Federation.

As the ATO HQ said earlier, one Ukrainian soldier was wounded in shelling in Donbas on Sunday, February 18.
