Kosovo clashes highlight Balkans' fragility

Fourteen policemen and one protester were injured.

The violence came after police hauled in Kurti, the head of the Vetevendosje ("self-determination") political party, for questioning.

The 40-year old politician was interrogated over an incident last Thursday, in which he set off a tear gas canister inside parliament, causing some MPs to faint.

He did it in protest against the Association of Serb Municipalities (ASM) - an EU-brokered deal to give quasi-autonomy to Kosovar Serb enclaves in Kosovo.

Following his release on Monday, he spoke briefly outside the parliament building, saying: "I call on you not to stop until we prevent the creation of the community".

Vetevendosje started out as a protest movement, daubing anti-EU and anti-government graffiti around Pristina.

But it became the third largest political party in Kosovo in last year's elections, winning 14 percent.

It says the ASM deal is the first step in the creation of an autonomous Serb entity in Kosovo, on the model of Republika Srpska in Bosnia.

It believes the EU and US are willing to sacrifice Kosovo's territorial integrity for the sake of better ties with Serbia in order to reduce Russia's influence in the Western Balkans.

It also says Western powers give Kosovo leaders, such as deputy PM Hashim Thaci, carte blanche on corruption in return for compliance on their agenda.

"The EU is feeding the little octopus [Serbia] so that it can separate it from the big octopus [Russia], but the problem is that the little octopus has its tentacles deep inside Kosovo", Kurti told EUobserver in a previous interview.

The ASM deal has prompted Albanian minority enclaves in Serbia to declare their own association - a move fiercely rejected by Serbia's nationalist leaders.

The Kosovo unrest also comes amid a simmering crisis in neighbouring Macedonia, where the main Albanian party, the DUI, of Ali Ahmeti has split in two amid calls for greater minority rights.

Meanwhile, Republika Srpska leaders in Bosnia are planning to hold a referendum on the authority of the federal court in what EU foreign ministers, on Monday, said "would challenge the cohesion, sovereignty, and territorial integrity of" the country.

Kosovo stability will also be tested when a new EU tribunal in The Hague starts work in early 2016.

The court is to indict former commanders of the KLA, the Kosovo guerrilla army which fought Serbia in the 1990s, on war crimes charges, including, potentially, Thaci himself, who stands accused, in a Council of Europe report, of running an organ-trafficking mafia.

The prospect raises concerns that ex-KLA fighters from Drenica, Thaci's home region in Kosovo, could take to the streets.

Thaci recently told EUobserver he will comply with the tribunal's work.

"The tribunal will dispel any doubt about our [the KLA's] past", he said, adding: "But we will do our utmost not to allow the perpetrators of crimes [Serbia] and the victims of crimes to become equals in the books of history".
