Kosovo police are questioning four suspects, including a U.S. citizen, about their alleged links with terrorism, they said Friday.
The four were arrested for illegal possession of weapons and endangerment, but "charges could be expanded" to include terrorism, pending an investigation, police spokesman Arber Beka said.
He says police found two Kalashnikov rifles and five hand grenades during the arrests early Friday in the western town of Prizren. Beka declined to comment on allegations in the local media that the suspects are linked to Islamist radicals.
Local media said the raid was executed in cooperation with the FBI, but Beka said police would not confirm or deny that.
"We cooperate with police from other countries in dealing with cases of organized crime and terrorism," Beka said.
Police also seized a laptop computer believed to contain information about the suspects' plans.
The arrests come a month after Kosovo police said they shared information with the FBI investigation that led to the arrest of a Kosovar in the United States, accused of plotting with six Americans to carry out terror attacks in other countries.
Earlier this year three ethnic Albanian brothers from the former Yugoslavia were each sentenced to life terms without parole for plotting to kill military personnel at New Jersey's Fort Dix. The men were arrested in May 2007.
Kosovo's ethnic Albanians are staunch supporters of the U.S. and see America as the driving force behind Kosovo's declaration of independence from Serbia last year.
