PRISTINA, Kosovo—Kosovo President Hashim Thaci, a wartime hero turned politician, resigned on Nov. 5 after learning that a tribunal in The Hague has confirmed a war crimes indictment against him.
Thaci told a news conference in the Kosovo capital, Pristina, that he felt his resignation is necessary "to protect the integrity of the state."
Thaci arrived at Pristina's military airport to be flown to The Hague, where he will be taken into custody by the Kosovo Specialist Chambers, the Kosovo-based newspaper Koha Ditore reported.
The move could bring political instability to Kosovo, a young democracy where the 52-year-old former guerrilla became the first prime minister in 2008 and was elected president in 2016.
Prosecutors hold Thaci responsible for nearly 100 murders of civilians during the 1998-99 war, when he was a Kosovo Liberation Army commander who fought the Serbian police and army; he denies any wrongdoing.
Thaci, a U.S.-backed national hero, embarked on his political career after leading the's KLA's battle against forces under the late Serbian President Slobodan Milosevic in 1998-1999.
Thaci has long enjoyed U.S. political support. Ties with the administration of U.S. President Donald Trump deepened in September when Kosovo and Serbia signed an economic relations deal at the White House.
Trump was given Kosovo's highest state honor for his role in securing the deal, and he boasted about bringing peace to the Balkans during his reelection campaign.
The European Union on Nov. 5 welcomed Thaci's cooperation with the Kosovo Specialist Chambers, where he is expected to come before a pretrial judge in the coming days.
Anger in KosoveMany in Kosovo oppose the war crimes court and see the KLA commanders as heroes.
"I think a big injustice is being committed here by putting on trial our liberators," economist Fejzullah Ibrahimi told Reuters at a market in Pristina.
NATO bombed Belgrade, Serbia, in 1999 with U.S. support to halt the killings and expulsions of ethnic Albanians from Kosovo by Serb forces.
Human rights watchdog Amnesty International says the indictment against Thaci gave hope to thousands of victims of the war "who have waited for more than two decades to find out the truth about the horrific crimes."
In Belgrade, lawmaker Milovan Drecun, who is chairman of the Serbian parliamentary committee for Kosovo, said the indictment proved that "establishing the truth about war crimes of the KLA and punishing those responsible is an irreversible process."
In July, Thaci met with prosecutors in The Hague to discuss the allegations against him. Another two Kosovo politicians and former KLA members—Rexhep Selimi, a deputy in the Kosovo parliament, and Kadri Veseli, the president of Thaci's Kosovo Democratic Party—also had indictments confirmed.
On Nov. 4, former KLA spokesman and veteran Kosovo politician Jakup Krasniqi was arrested and transferred to The Hague on charges of war crimes and crimes against humanity, the court said.
