A member of an elite Macedonian police unit was killed and two others were wounded when their car was shot at in the capital Skopje on Thursday, police said.
"Attackers opened fire from a moving vehicle at the police jeep," said police spokesman Ivo Kotevski. "Three officers were wounded, and one of them died on his way to hospital."
Kotevski said the motive for the attack in a Skopje suburb was unknown.
Tensions remain in Macedonia in the wake of a 2001 insurgency by ethnic Albanian guerrillas fighting for greater rights for the country's 25 percent Albanian minority.
Organised crime is also rife in the former Yugoslav republic.
