An audio recording purporting to be from the Islamist militant group al-Qaeda in the Arabian Peninsula (AQAP) claimed responsibility on Sunday for a fatal shooting in December at a US naval base in Pensacola, Florida, but provided no evidence.

"We congratulate our Muslim nation and embrace the operation of the martyr hero, the daring knight Muhammad bin Saeed Al-Shamrani," said the audio, released by al-Qaeda’s Yemen branch.

Three people were killed in the shooting.

Reuters was unable to verify the authenticity of the recording.
