BELGRADE, Serbia — Air Serbia says it will resume flights between Belgrade and Zagreb on Friday after a 23-year break.

Flights between the Serbian and Croatian capitals were discontinued in 1991 because of the war between the two former Yugoslav republics.

The Serbian national carrier, partly owned and operated by United Arab Emirates’ Etihad Airways, says it will offer two daily flights with ATR72 turboprop aircraft.

During summer, Air Serbia flies to the Croatian Adriatic resorts of Dubrovnik and Split. Croatian Airlines says it has no plans to fly to Belgrade.

Political tensions remain high between Serbia and Croatia, although their economic and other ties are on the rise.
