The 22-year-old informed Australian team officials of her decision on Tuesday, the Australian Associated Press (AAP) said, two days after two Taiwanese nationals were wounded when suspected militants opened fire on a tourist bus outside a mosque.

"She had prepared her whole season around winning this thing, she even knocked back some Diamond League meets because it affected her training,” he said.
Samuels won gold at the world titles in Berlin last year with a personal best of 65.44M. She increased that PB to 65.84M early in 2010.
