Riot police charged into the crowd after voilence broke out in the stands during Serbia's clash with England. The incident took place in the home section of the stadium in Belgrade, far away from where the visiting fans were based.
ITV commenator Sam Matterface broke the news on the live broadcast and said: "There is a stream of riot police running into the home section of the crowd." He then added that a child had to be lifted out of the melee while the authorities rushed to the scene. TV images did not show the incident.
Touchline reporter Gabriel Clarke clarified that the situation was due to political differences.
"The disturbance happened in the main stand and it was rather unnervy for a few minutes," he said. "A few Serbians ran across that stand, there were families involved as well. Some children had to be moved on.
"It was Serbian fans arguing between themselves. It was politically charged, pro and anti government.The police have moved in and calmed the situation."
There have been no reports of any serious injuries.

There is huge political unrest in Serbia over controversial president Aleksandar Vucic. The government are so polarising that Serbian national team manager Dragan Stojkovic was booed as he walked out of the tunnel ahead of kick-off because of his views on the situation.
Many Serbian cities have seen a string of protests as they demand a snap pole to try and our president Vucic.
Sixteen people were killed at a protest last November when the roof of a renovated train station fell through. Since then the protests have intensified with corruption accusations being thrown at the party in power.
Serbia's biggest sporting icon, Novak Djokovic, voiced his concern following the death of those protestors and there are reports that he has also been targeted by his own country's government.
Meanwhile, England romped to victory in Serbia thanks to goals from Harry Kane, Noni Madueke, Ezri Konsa, Marc Guehi and Marcus Rashford.
