Norway's Kon-Tiki museum to return thousands of Easter Island artefacts

Explorer Thor Heyerdahl collected many items in his effort to prove South American migration theory

Norway has agreed to hand back thousands of artefacts removed from Easter Island by the explorer Thor Heyerdahl during his trans-Pacific raft expeditions in the 1950s.

An agreement was signed by representatives of Oslo's Kon-Tiki Museum and officials of Chile's culture ministry at a ceremony in Santiago as part of a state visit by Norway's King Harald V and Queen Sonja.
