SKOPJE (Reuters) - About 40 armed men wearing uniforms of a disbanded ethnic Albanian guerrilla army from Kosovo took several police officers hostage in northern Macedonia overnight, Macedonian police said on Tuesday.
The men left the police post near Macedonia's border with Kosovo after several hours.
Macedonian Interior Ministry official Ivo Kotevski told a news conference that the gunmen said they were part of the guerrilla Kosovo Liberation Army (KLA).
Speaking in Albanian, they told their captives "We will have an Albanian state".
"This morning, Macedonian state institutions were the target of a terrorist act," Kotevski said.
The incident was reminiscent of an insurgency in Macedonia in 2001, when security forces fought rebels demanding greater rights for the former Yugoslav republic's large ethnic Albanian minority.
That conflict followed a 1998-99 war involving the KLA in neighboring majority-Albanian Kosovo, a former province of Serbia.
A peace accord in 2001 ended the fighting in Macedonia. The guerrillas laid down their arms and entered politics in exchange for greater rights and representation for an Albanian minority estimated to account for about 30 percent of Macedonia's 2 million people.
Macedonia was promised integration with NATO and the European Union but progress has been blocked by a dispute with Greece over Macedonia's name, which it shares with a northern Greek province.
Ethnic tensions remain, fueled by frustration at the lack of progress toward the European mainstream and the jobs and prosperity many in Macedonia hope will follow.
