Belgrade: Serbian President Tomislav Nikolic had to cancel an official visit to the Vatican on Friday when his plane developed engine trouble and had to turn around and return to Belgrade.
The visit during which Nikolic was to meet Pope Francis was "annulled due to a failure of an engine of the plane", a spokesman for the presidency said.
The presidential jet landed safely Belgrade Surcin airport.
Nikolic`s visit to the Holy See was aimed at confirming the "good relations between the Vatican and Serbia" whose 7.1 million inhabitants are mostly Orthodox Christian, Serbian authorities said earlier.
The Serbian head of state attended the inauguration ceremony of Pope Francis in March 2013.
