Kosovo's Prime Minister Ramush Haradinaj said on Friday he was resigning after being called to The Hague war crimes court linked to Kosovo's independence struggle.
"The reason for this decision is because of a call I have received from a specialist chamber as a suspect," Haradinaj said.
The special court in the Hague was set up in 2015 to try ex-Kosovo Liberation Army (KLA) guerrillas for alleged atrocities in the war that led to independence from Serbia.
The specialist chamber is funded in part by the European Union.
The Kosovar president, Hashim Thaçi, wrote in a Facebook post that he had learned that the special court planned on interviewing former members of the KLA.
Thaçi said he respected the prime minister's decision but said he believed in the "purity" of the war and in the "high moral values of the soldiers of freedom".
Haradinaj said he would travel to The Hague next week. This is the second time he has had to resign as prime minister.
During the Balkan wars, a paramilitary group the Kosovo Liberation Army (KLA) formed. The group fought against Serbian authorities in a violent war that was only ended after NATO launched a 77-day air campaign against Serbia.
Serbia still does not recognise Kosovar independence.
