Mourning the death of Shahnaz Nazli, a courageous teacher shot for wanting to ensure girls have the right to go to school, we call on the president and government of Pakistan to end the killings and violence that prevent girls' education and to ensure all girls can go to school.
We call for all girls and all teachers to be protected and given security to enable them to enjoy their basic right to be educated.
