US Vice-President Joe Biden has said the killing of four marines and a sailor in Chattanooga in July was the work of a “perverted jihadist”, despite no official determination of motive.

Speaking at a memorial service in the Tennessee town, Mr Biden also called the suspect a “perverse ideologue”.

US authorities say Mohammad Youssuf Abdulazeez acted alone when he attacked two military facilities in Chattanooga.

But the FBI has said it has not yet been able to establish a motive.

Mr Biden was joined by US Defence Secretary Ashton Carter and families of the victims for the service, a month on from the 16 July attack.
