An unidentified flying device, which local media reported could be a Soviet-era drone, crashed in the Croatian capital Zagreb late Thursday, police said.
Several parked vehicles were damaged in the accident that occurred around 9:00 pm (2200 GMT) Thursday, but there were no reports of anyone injured, an interior ministry statement said on Friday.
Police rushed to the scene after residents reported that they “felt a detonation preceded by a fall of an object from the sky,” the statement said.
In a park close to the Jarun lake, some six kilometers (four miles) from the city center, police found a crater and two parachutes nearby, it added.
Local media quoted military aviation experts as saying that the device that crashed could have been a Soviet-era Tu-141 reconnaissance drone used by Ukraine.
Police sealed off the site and temporarily halted public transport in the area.
Zagreb is located some 550 kilometers flying distance from the border with Ukraine, which Russia invaded on February 24.
