On Tuesday night an emotional Jimmy Kimmel dedicated his monologue to the controversial killing of Cecil the lion in Zimbabwe.

Yesterday it was revealed that American dentist Walter James Palmer was the hunter who shot and killed the 13-year-old male lion after luring him out of Hwange National Park.

Zimbabwe officials said they are now searching for Palmer. Police spokesperson Charity Charamba said the Minnesota dentist faces poaching charges, the Associated Press reported.

Palmer has released a statement insisting that the local hunters he worked with had appropriate permits, and that no aspect of the hunt was outside of the law.

Kimmel took the opportunity on his show last night to criticise Palmer.
