Human rights campaigner Malala Yousafzai, who studied at Oxford University, has expressed "complete shock" as the Taliban takes control of Afghanistan.

She tweeted: "I am deeply worried about women, minorities and human rights advocates. Global, regional and local powers must call for an immediate ceasefire, provide urgent humanitarian aid and protect refugees and civilians."

She survived being shot in the head, neck and shoulder while travelling home from school by Taliban soldiers for saying girls should be allowed to stay in education.

She was writing an anonymous diary about life under the extremists.

After recovering from her near-fatal injuries, she and her family relocated to Birmingham.

In 2014, she became the youngest person ever to win the Nobel Peace Prize, at the age of 17.

Three years later she accepted a place to study politics, philosophy and economics at Lady Margaret Hall.
