One man was killed another was wounded in the shelling of a bus from small-arms near Olenivka in the part of Donetsk region temporary beyond Ukrainian government control, observers of the OSCE Special Monitoring Mission reported.

"On 21 January, upon arriving at a checkpoint on the south-western edge of Olenivka at 12:30, the SMM was accompanied by an armed 'DPR' member in military-style clothing to a bus stop 40m north of the checkpoint. The SMM saw a hole in a window on the driver's side of a bus, which the SMM assessed as caused by a bullet," the SMM said in a report for January 21 posted on the organization's website.

The SMM later saw another bullet hole on the same side of the bus. According to the observers, the bus had 40-50 passengers on board.

"The SMM assessed that the bus was hit by small-arms fire originating from a westerly direction. Then, the 'DPR' member accompanied the SMM to an 'emergency service' tent next to the bus stop, where the SMM saw two men (both 58 years old): one had blood covering the left side of his face and was holding gauze to it and the other had gunshot wounds in his neck and left cheek," the report reads.

The SMM saw medical staff trying to resuscitate the latter man who was losing blood heavily and had trouble breathing.

"Before departing from the area, the 'DPR' member told the SMM that the man with the gunshot wounds in his neck and left cheek had died and that the other man had been transported to a hospital in Donetsk," the mission said.
