Amnesty International said it authenticated two videos it received last week showing graphic images of a beheaded Cameroonian security officer. The videos also captured a man who said he belonged to Ambazonia Liberation Forces, a separatist group demanding a secession from the West African country.
CNN has not independently authenticated the videos and is unable to immediately reach Ambazonia Liberation Forces for comment.

Witnesses said they heard gunfire exchanged on the night of the incident.
