Change to rape law
The government has recently amended the law with death penalty as the highest punishment for rape.
The much-talked-about 'Women and Children Repression Prevention (Amendment) Bill, 2020' was passed in Parliament on November 17.
Countrywide protests against sexual violence against women, sparked by gang rape incidents at MC college and another in Noakhali, prompted the government to make the much-needed change.
Nearly a thousand rape incidents, including over 200 gang rapes, were reported between January and September this year, according to Ain o Salish Kendra (ASK).

Forty-five of the victims were killed after rape and 12 others took their own lives. Three women and nine men were killed for protesting against the incidents of sexual harassment, ASK said.
Numerous incidents of sexual assaults go unreported in the country. Experts say a strict implementation of the law is needed to deter incidents of rape and other forms of violence against women.
