Prince William warns poachers are outrunning efforts to stop wildlife trade

Animals are still being killed in horrifying numbers despite global efforts to stop the poaching crisis, says prince at Hanoi summit

Poachers killing Africa's rhinos and elephants are still one step ahead of efforts to stop the multibillion wildlife trade, Prince William has warned.

Traffickers have become more sophisticated and increasingly brutal, and animals are dying in "horrifying numbers", the Duke of Cambridge told an international wildlife summit in Hanoi, Vietnam on Thursday.
