President of Serbia and Supreme Commander Aleksandar Vucic will visit Serbian Army units in the Ground Safety Zone and elsewhere in southern Serbia, reports Serbian media.

The visit will happen "in the next 72 hours," reports said late on Thursday.

The Ground Safety Zone was established after the 1999 war and runs along the administrative line between Kosovo and central Serbia.

The Ministry of Defense announced that Vucic would tour the area together with Defense Minister Aleksandar Vulin and army chief Milan Mojsilovic and visit several units.

This is taking place as Pristina is preparing to announce the formation of an army in Kosovo - a move Serbia strongly opposes.
