Memorial service held for IS victim Steven Sotloff
Nearly 1,000 mourners including relatives, friends and politicians, have attended a memorial service in Florida for US journalist Steven Sotloff, who was killed by IS militants.
The Islamic State released a video on Tuesday showing the murder of Mr Sotloff.
He is the second American journalist to be beheaded in two weeks over the group's confrontation with the US over air strikes in Iraq and its foreign policy.
Footage of James Foley being beheaded on August 19 shocked the world.
