Serbia has begun talks with Russia over the acquisition of four Mil Mi-17 transport helicopters and the same number of Mi-35 attack rotorcraft.
The likely purchase was revealed by Belgrade's defence minister Aleksandar Vulin, after a meeting with his Russian counterpart Sergey Shoygu in Moscow.
Previous indications from Serbia's defence ministry were that the order would probably only be for six Mi-17s.
Currently, the nation's sole attack helicopter inventory comprises a pair of Mi-24Vs that are in a non-flyable condition.
