The Duchess of Cambridge has been named as one of the most influential people in the world by Time Magazine.
Months after Malala was shot on her way home from school, a teacher has been killed by gunmen in the same region of Pakistan.
Malala Yousufzai, the Pakistani schoolgirl shot in the head by the Taliban, has gone back to school for the first time since her attack.
The 15-year-old, who was shot in the head by the Taliban, said it was the happiest moment of her life.
ITV News' Sejal Karia reports:
The Pakistani schoolgirl shot in the head by the Taliban for fighting for the right of girls to be educated will publish her memoir later this year.
Malala Yousafzai will describe in her own words what happened back in October 2012 and how she was determined not be intimidated by extremists. Malala said: "I want to tell my story, but it will also be the story 61 million children who can't get education."
When Malala was shot the bullet entered just above her left eye and ran along her jaw, "grazing" her brain. It was later removed by surgeons in Pakistan before she was flown to the UK.
This is the text of the petition Malala Yousufzai and her father have signed:
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.
Malala Yousufzai and her father Ziauddin have become the first signatories of a petition calling for better protection for teachers and students in Pakistan.
The petition, addressed to the president of Pakistan, is in response to the killing of a teacher on her way to work at a girls' school in Pakistan's north-west tribal region on Tuesday.
The killing took place not far from where Malala herself was shot in the head as she returned from school in October 2012.
Gunmen have shot dead a teacher as she walked to work at a school for girls in Pakistan's north-west tribal region on Tuesday.
Shahnaz Nazli, 41, was a teacher at the government-run primary school for girls in Shahkas, near Jarmrud in the Khyber tribal region.
While there has been no immediate claim of responsibility for the killing, attacks on girls' schools are common in this region where Islamist militants oppose education for women.
Malala Yousafzai, the Pakistani schoolgirl shot by the Taliban for fighting for the right of girls to be educated, spoke of her pride today as she returned to school for the first time since the attack.
Speaking on her way to Edgbaston High School for Girls in Birmingham, the 15 year old said, "It is an honour for me and it's what I dreamed ... I'm on my way to my dream".
