The OSCE mission had earlier written on its website that four of their armored cars had been burned apparently as a result of an arson attack.
No official comment about the nighttime incident has so far been provided by the OSCE mission.
The incident occurred in the parking lot of the Park Inn hotel the members of the OSCE mission are staying at.
“We have provided additional protection for members of the OSCE mission and will make every effort to prevent any such incidents from happening against,” Denis Pushilin, Vice Speaker of the People Council of the Donetsk People’s Republic, told the local news agency on Sunday.
The mission has no plans to withdraw from Donetsk at this stage.
