Sexual violence against children
Sexual violence against children has become a burning issue in recent years as Bangladesh saw a spike in incidents of child rape and sexual assault on children last year, according to Bangladesh Shishu Adhikar Forum (BSAF).
At least 1,005 incidents of child rape were recorded last year, a 76.01 percent increase compared to the year before, BSAF said in its yearly report ‘State of Child Rights in Bangladesh’.
On average, about 84 children became victims of rape in every month of 2019.
BSAF said the number of incidents was higher compared to previous years. Of the victims, 133 were aged between one and six years. Most of the rapes were reported in Dhaka district.
The data were collected from 15 national dailies between January and December.
Between 2015 and 2019, a total of 3,136 children fell victims to rape – 52 incidents every month on average. But verdicts in only 164 cases were delivered – 27 of them last year.
Highest punishment for rape
The increasing rate of rape incidents fuelled countrywide protests against sexual violence against women and children that prompted the government to amend the law with a provision for death penalty for rape.
The much-talked-about 'Women and Children Repression Prevention (Amendment) Bill, 2020' was passed in Parliament on November 17.
