Surprisingly, 116 of the victims were aged 6 years or lower.
Overall, 1,627 incidents of rape were documented last year. Fifty-three of them were killed after rape and 14 of the victims took their own lives, ASK data showed.
The data was collected from various newspaper reports. But the actual number is believed to be higher as many victims choose not to report assaults fearing their safety.
