Yousafzai said in a brief speech at a ceremony at Prime Minister Shahid Khaqan Abbasi’s office that she will continue to campaign for the education of girls and asked Pakistanis to be united on issues like providing better health care and education. She said she remembered having to leave Pakistan for treatment after she was attacked.
