A military spokesman said one Ukrainian serviceman had been killed and two others received dangerous wounds during an alleged militants attack in the area of the village of Shyrokyne, Donetsk region, on Saturday morning.

"Yesterday the enemy on eight occasions opened mortar and small-arms fire on Ukrainian positions in the vicinity of Shyrokyne. Yesterday none of our personnel was hurt. At 6:25 hours today the enemy went over to D-30 122-millimeter guns. These are banned by the Minsk agreements… Around 7:00 hours a member of the Donbas Battalion of the National Guard, a 42-year-old man from Kyiv, was killed. Another two members of the Donbas Battalion are at one of the hospitals in Mariupol in severe condition," Dmytro Horbunov, spokesman for the Ukrainian army's Sector M, told Interfax.

He said the wounded servicemen's commanders were going to send them to a Defense Ministry hospital.

Horbunov also said ceasefires had been established on several occasions in the Shyrokyne area at the proposal of militants but that the latter had themselves violated them.

"This week alone, the enemy on 12 occasions proposed a ceasefire and used that time to evacuate their wounded, redeploy, replenish their arsenals. Then they themselves would open fire. Those are banned methods of warfare, methods that our forces would never have used," the spokesman said.
