US dentist 'deeply regrets' killing famous lion

Cecil the lion was distinctive for his black mane

I deeply regret that my pursuit of an activity I love and practice responsibly and legally resulted in the taking of this lion

– Walter Palmer

An American dentist has admitted his regret after it emerged he could have killed one of Africa's most famous lions.

Conservationists in Zimbabwe have accused prolific game hunter Walter Palmer of being the alleged killer of Cecil, the star attraction at the Hwange national park.

Palmer is thought to have paid $50,000 (£32,000) to guides for the chance to kill Cecil around July 6. It is said he first shot at the lion with a bow and arrow but when that failed they tracked him down and shot him with a gun 40 hours later.

He released a statement late on Tuesday saying that he thought everything about his trip was legal and he wasn't aware of the animal's status until the end of the hunt.
