Josip Briski, 27, was a member of a Croatian contingent deployed in Afghanistan as part of a US-led mission.

He was killed on Wednesday when a suicide attacker hit his convoy, injuring two other Croatian soldiers, Croatia's Defence Minister Damir Krsticevic said.

A US Air Force plane brought Briski's coffin draped in the red, white and blue Croatian flag to Zagreb airport where it received military honours, Croatia's Hina news agency reported.

President Kolinda Grabar Kitarovic attended the airport ceremony along with other ministers, NATO representatives and family members.

A commemoration is scheduled for Friday in the capital Zagreb and the soldier's funeral will be held on Saturday.

Two other Croatian soldiers were wounded in the attack in Kabul. They were said to have serious but not life-threatening injuries, Krsticevic said on Wednesday.

Violence in Afghanistan has flared in recent weeks as the United States leads an effort to forge a peace deal with the Taliban after nearly 18 years of war.

About 100 Croatian soldiers are deployed in Afghanistan as part of the US Resolute Support Mission. Coalition soldiers help train and advise their Afghan partners.
