Anarchists and riot police have clashed in Greece after around 2,000 protesters from across the Balkans marched in the northern city of Thessaloniki against nationalism.
Police used tear gas and threw stun grenades at the protesters, who also barricaded themselves at the University of Thessaloniki.
Police are prohibited by law from entering the campus to make arrests.
Nationalist tensions remain pervasive in the Balkans, and Greece and neighbouring Macedonia have seen recent protests over a decades-long name dispute.
Greece argues that Macedonia’s name in its current form implies a territorial claim against its own region with the same name.
