Machetes fail to maim this human spirit

When a slight woman with cropped dark hair walked on to a stage in a London hotel on Thursday evening, she was greeted with an immediate standing ovation. Four months ago, Rafida Bonya Ahmed and her husband, Avijit Roy, were attacked with machetes by Islamic extremists in the Bangladeshi capital, Dhaka. Roy died and Ahmed was seriously injured, receiving deep wounds to her head.
