PRISTINA, Kosovo—A special international court said that a former commander of the separatist fighters in Kosovo’s 1998-1999 war has been arrested as part of a war crimes and crimes against humanity investigation stemming from the conflict with Serbia.Former Kosovo Liberation Army (KLA) commander Salih Mustafa was arrested based on a “warrant, transfer order, and confirmed indictment issued by a pre-trial judge,” the Kosovo Specialist Chambers, based in The Hague, said on Sept. 24. The court’s statement didn’t identify the charges on which he was indicted.
The court said Mustafa would be transferred to its detention facilities in The Hague and “appear before the pre-trial judge without undue delay.” He is the first ethnic Albanian to be arrested on war crimes charges arising from the 1990s conflict.
The Kosovo Liberation Army was made up of ethnic Albanian rebels who wanted Kosovo’s independence from Serbia. Mustafa oversaw fighters in the Llapi area, 35 kilometers (20 miles) north of the capital, Pristina.
He later served as intelligence chief of the Kosovo Security Forces, military troops created in 2009 as a transitional unit before becoming a regular army.
The Kosovo Specialist Chambers and an attached Special Prosecutor’s Office, or SPO, was established five years ago to look into allegations that KLA members committed war crimes and crimes against humanity.
The European Union Rule of Law Mission in Kosovo, or EULEX, which is in charge of the court, said it had “provided operational and logistic support to the SPO in line with its mandate and in accordance with the Kosovo legislation.”
Hysni Gucati of the war veterans’ association said Mustafa’s family reported he was arrested early on Sept. 24 and taken to The Hague.
“To us, the court and its actions are unacceptable,” Gucati said.
The association has said it anonymously received thousands of confidential files during the past two months, which contain names of witnesses and also draft charges against former top KLA commanders. It wasn’t clear whether the files were stolen or leaked by someone involved in the investigation.
The war veterans said they would make them public, a move that a court spokesman warned would undermine the proper administration of justice. The Specialist Prosecutor’s Office is investigating how the association came into possession of the documents.
Office spokesman Christopher Bennett said authorities were “vigorously investigating and prosecuting individuals who commit any such crimes.”
Prosecutors in The Hague also have indicted Kosovar President Hashim Thaci, former parliamentary speaker Kadri Veseli, and others for crimes that include murder, enforced disappearances, persecution, and torture. Both men have denied committing any war crimes.
The 1998-1999 war for Kosovo’s independence from Serbia left more than 10,000 people dead—most of them ethnic Albanians from Kosovo. More than 1,600 people remain unaccounted for. The fighting ended after a 78-day NATO air campaign against Serbian troops.
Kosovo, which is dominated by ethnic Albanians, declared independence from Serbia in 2008, a move recognized by many Western nations but not Serbia or its allies Russia and China.
