Pristina - Kosovo authorities said on Friday a potential car bombing was thwarted in Pristina on Christmas day when police stopped a Serbian in a vehicle packed with a large quantity of explosives.
Interior Minister Skender Hyseni said in a statement that police had seized more than 12kg of explosives on Thursday, and noted had they been "detonated in a public place, human casualties would have been enormous".
Police spokesperson Baki Kelani told reporters the car was "filled with a huge quantity of explosive material", and was stopped late on Thursday while being driven through a residential area in the capital that houses many embassies and diplomats.
A high-level police official involved in the probe who asked not to be named told AFP that the explosive "could be ignited remotely", and is "of a type and quantity suitable for the destruction of large objects".
Kosovo's prosecutor has launched a probe into what is being considered a plotted "terrorist attack".
Hyseni said in his statement the car's driver "is a citizen of Serbia...with permanent residence in Belgrade, and [carrying] Belgrade licence plates on his car".
The driver - born in 1968 and identified only by the initials SG - was immediately arrested, Kelani said.
Police refused to speculate on the intended target.
Local media said a possible target could have been the Catholic cathedral the city centre close the the arrest site, which was packed with hundreds of Christmas day worshippers.
