A section of Romanian fans held up a banner that read ‘Kosovo is Serbia,’ while some members of the home end chanted “Serbia, Serbia,” according to Reuters.
The game was temporarily paused, with the referee taking the players off the field.
In a statement to CNN Sport, the Romanian Football Federation said the banner and chants were the actions of “a group of ultras illegally introduced into the stadium.”
It also said it “firmly condemns provocative messages of a political, ideological, religious or insulting nature” and confirmed law enforcement had identified those involved.
“A legal investigation will be conducted according to the facts committed,” it added.
UEFA told CNN that the official reports from all of Tuesday’s matches were “currently being reviewed.”
In a statement to CNN Sport, the Football Federation of Kosovo condemned the matter and stressed that “through football we build bridges between people, we should not tear them down.”
It stated that the fans who carried out these acts “denigrated” the match through the “language of hatred.”
It also confirmed that it had requested the match be suspended until all banners were taken down and chants stopped.
“The Football Federation of Kosova has also addressed the Disciplinary Commission of UEFA with the request that adequate measures be taken in relation to the nationalist chants, banners and hate language expressed by the fans of the Romanian National Team,” it said.
Kosovo declared independence from Serbia in 2008, following the 1998-99 war in which Kosovar Albanians attempted to break from what was then the Federal Republic of Yugoslavia, made up of today’s Serbia and Montenegro. NATO intervened in the war to protect Kosovo’s Albanian majority.
Serbia views Kosovo as a breakaway state and does not recognize its independence. Kosovo’s Serbs view themselves as part of Serbia, and see Belgrade as their capital, rather than Pristina.
Meanwhile, Romania does not recognize Kosovo, which has caused tension between the two.
The game was eventually restarted, with Kosovo being reduced to 10 men just before the half-time interval when Vedat Muriqi was sent off after receiving a second yellow card for a foul.
Although it took much of the second half for the hosts to break the deadlock, Romania finally exploited its numerical advantage and moved ahead in the 83rd minute through Nicolae Stanciu, before Valentin Mihăilă doubled the lead in added time.
Romania moves into second place on 12 points in Group I, while Kosovo dropped to fifth position and remain winless on four points.
