Pop star Rihanna describes assault horror

Chart star Rihanna has described the horror she felt as her ex-boyfriend Chris Brown was biting and punching her during a violent argument, saying she saw "no soul in his eyes".

"There was no person when I looked at him," the 21-year-old singer said during an interview on US TV network ABC's primetime news show 20/20 and also on Good Morning America.

"He had no soul in his eyes. Just blank."
