Malala Yousafzai has completed her first day at Oxford University, England.
Five years after she was shot in the head by militants in Pakistan, the 20-year-old Nobel Peace Prize winner tweeted a picture ahead of her class at the prestigious institute.
In 2012, she was shot on the way home from school after writing an anonymous diary about life under Taliban rule. After recovering from her near-fatal injuries, she and her family moved to Birmingham in the midlands of England.
"Five years ago, I was shot in an attempt to stop me from speaking out for girls' education. Today, I attend my first lectures at Oxford," Malala wrote on Twitter.
Within minutes her picture was shared more than 10,000 times as people around the world wished her good luck.
"Congratulations Malala. You stand as a beacon of hope to women and all of us in this world. Enjoy university!", wrote one user.
Malala became an international symbol and advocate for the fight to improve girls' education across the globe.
Earlier this year she was made the youngest ever UN Messenger of Peace and in August she accepted her place at Lady Margaret Hall college to study philosophy, politics and economics.
