Pakistan's teenage rights activist Malala Yousufzai, shot in the head by Taliban, has managed to stand with help for the first time and is also able to write, doctors treating her at a UK hospital said today, while warning that "she is not out of the woods" yet.

15-year-old Malala "is now well enough... she is happy, in fact, keen for us to share quite a lot of clinical detail with you," Dr David Rosser told reporters.

"She's communicating very freely, she's writing," he said. The girl has managed to stand with help for the first time since the October 9 attack.

Malala was "doing very well" but there were still some concerns about her smooth recovery, he said, adding that she was "not out of the woods" yet.

The schoolgirl, who along with two of her classmates was attacked in the restive Swat region of northwest Pakistan as they made their way home from school 10 days ago, was flown to the UK on Monday following a surgery at a Pakistani hospital during which a bullet lodged near her spine was removed.

"She is still showing some signs of infection, which is probably related to the bullet track. (There is) some infection in the bullet track, which is our key source of concern," Dr Rosser said.
