More than six tons of confiscated ivory including tusks, carvings and jewellery have been crushed in the US.
Thousands of items accumulated over the past 25 years were dumped into a steel crusher at the National Wildlife Property Repository north of Denver.
Adam Roberts, Executive Vice President of Born Free USA said: "Any time we can remove ivory from the marketplace, it is a win for elephants."
