Serbia has held a funeral for Yugoslavia's last king, Peter II Karadjordjevic, who fled the country at the start of World War II and died in the U.S. in 1970.

The former king's remains, and those of his wife, mother and brother, were interred in the family tomb Saturday in the village of Oplenac, in central Serbia.

Officials described the ceremony as an act of reconciliation and unity.

After fleeing Yugoslavia, the former king never returned because Communists took over the country at the end of the war. He died in exile at the age of 47 and was buried at a Serbian Orthodox Church monastery in Libertyville, Illinois — the only European monarch laid to rest on U.S. soil.
