Kenyan President Uhuru Kenyatta burns thousands of elephant tusks and rhino horns, seeking a world ban on their trade.
Kenya's president set fire to thousands of elephant tusks and rhino horns on Saturday, destroying a stockpile that would have been worth a fortune to smugglers and sending a message that trade in the animal parts must be stopped.
Plumes of smoke rose as the flames took hold of tusks piled up in a game reserve on the edge of the capital Nairobi, destroying 105 tonnes of ivory from about 8,000 animals, the biggest ever incineration of its kind.
President Uhuru Kenyatta dismissed those who argued Kenya, which staged its first such burning in 1989, should instead have sold the ivory and the tonne of rhino horn, which by some estimates would have an illegal market value of $150 million.
"Kenya is making a statement that for us ivory is worthless unless it is on our elephants," he told dignitaries before setting light to the first of almost a dozen pyres.
Kenya is seeking a total world ban on ivory sales when the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) meets in South Africa later this year as poaching poses an increasing risk to the species.
CITES banned commercial trade in African elephant ivory in 1989, but since then has permitted one-off sales.
Kenyatta's call for an ivory trade ban was backed by Ali Bongo, President of Gabon, home to the forest elephant.
"To all the poachers, to all the buyers, to all the traders, your days are numbered," Bongo said at the ceremony.
Illegal hunting spiked in the three years to 2012 when about 100,000 elephants were killed, the equivalent of more than 33,000 a year.
In the 1970s, Africa had about 1.2 million elephants, but now has 400,000 to 450,000.
The situation for rhinos is more precarious. There are fewer than 30,000 left across Africa and one species, the Northern White Rhino, is on the brink of extinction. The last three are kept in Kenya under heavy guard.
Kenya relies on tourism, with many drawn to safaris at luxury camps by the trove of animals Kenya boasts, particularly the "Big Five" - elephant, rhino, leopard, lion and buffalo.
Poachers in Kenya can sell the horns of a single dead rhino for the equivalent of about $50,000 in local markets, earning in one night what would take them many years in regular employment.
