'Back with my eyes open': Malala visits Pakistan district where she was shot

"I left Swat with my eyes closed and now I am back with my eyes open," she told AFP, referring to how she was airlifted out in a coma after the attack in 2012.

"I am extremely delighted. My dream has come true. Peace has returned to Swat because of the invaluable sacrifices rendered by my brothers and sisters," she said at a school outside Mingora, the district's main town, where she was escorted by the Pakistani military.

The brief trip by the 20-year-old Nobel laureate is a highly symbolic moment for Pakistan, which regularly touts Swat as a success story in its long battle with extremism as it defends itself against accusations by the US and others that its northwest remains a safe haven for militancy.

The visit - on which she was accompanied by her father, mother, and two brothers - was kept tightly under wraps.

After flying by army helicopter from Islamabad, she met with friends and family before visiting the all-boys Swat Cadet College Guli Bagh, a military-run school some 15 kilometres (nine miles) outside Mingora.

I left Swat with my eyes closed and now I am back with my eyes open... I am extremely delighted. My dream has come true. Peace has returned to Swat because of the invaluable sacrifices rendered by my brothers and sisters

There she lingered some 45 minutes, taking photographs, before travelling back to Islamabad. The entire visit is believed to have lasted just over two hours.

Mingora is where Malala's family was living and where she was attending school on October 9, 2012, when a gunman boarded her school bus, asked "Who is Malala?", and shot her.

She was treated first at an army hospital then airlifted to the British city of Birmingham.

Her near-miraculous recovery, and tireless career as an education advocate, have since turned her into a global symbol for human rights, and in 2014 she became the youngest person ever to be awarded the Nobel Peace Prize when she was just 17.

"I am unable to believe I am back in Swat and meeting my own people," her father Ziauddin Yousafzai said, in comments echoed by her mother Toor Pekai.

The trip comes two days after Malala, currently a student at Oxford University in Britain, made her emotional return to Pakistan, where her surprise visit has been met with widespread joy and pride.

She broke down in tears as she made a televised speech on Thursday, saying it was her "dream" to be back, and has vowed to Pakistani media that she will return permanently after she has completed her education.

However she has also been met with pockets of intense criticism. Malala is widely respected internationally, but opinion is divided in Pakistan, where some conservatives view her as a Western agent on a mission to shame her country.

There had been much speculation within the country over whether Malala would go to Swat during her visit.

The mountainous region, once a prized tourist destination famed for its pristine scenery, was overrun by the Pakistani Taliban in 2007.

The militants imposed a brutal, bloody rule, but the army drove them out in 2009. Recently restrictions on tourists visiting the area were lifted.

However security has remained fragile, as the assault on Malala three years after the military operation demonstrated. In February this year 11 military personnel were killed in an attack, and analysts have warned the militants still have a presence there.
