The Organization for Security and Cooperation in Europe (OSCE) says a group of its monitors was shot at by "uniformed personnel" in eastern Ukraine, RFE/RL reports.
The OSCE said in a statement that a uniformed man on the back of a flatbed cargo truck fired two shots in the direction of OSCE vehicles as they were driving on November 19 near the government-held town of Maryinka, some 15 kilometers west of the rebel-held city of Donetsk.
"The bullets struck about two meters from the second OSCE vehicle," the statement said, adding that the convoy left the area immediately.
The OSCE did not assign blame to government forces or pro-Russian separatists, but said the incident occurred in government-held territory.
OSCE monitors are observing a much-violated September 5 cease-fire in the conflict that the UN says has killed more than 4,100 people in eastern Ukraine since April.
