British doctors treating a teenage Pakistani education activist for a gunshot wound to the head said Saturday they were still upbeat about her progress. An update provided by Queen Elizabeth Hospital in Birmingham, England, said Malala Yousufzai remained on medications and that doctors said she needs further rest before having reconstructive surgery to repair the part of her skull damaged by a bullet fired by a Taliban gunman, GEO News reported. The hospital statement said the girl wanted to thank all those who have helped her, as well as those who have sent her their best wishes, the Pakistani television channel said. Malala is unable to speak because of a breathing tube in her windpipe but she can write, GEO News said. Her doctors have said she is doing well and has been able to stand with some help, but have expressed concern about signs of infection along the track of the bullet that grazed her brain and have warned she's not out of the woods yet. The 15-year-old girl was flown from Pakistan to Britain Monday.
