Nobel Peace Prize winner Malala Yousafzai, who was nearly murdered in 2012 over her efforts to promote education for girls in Pakistan, is now working to give Syrian refugee children a chance to go to school. More than three million children have been affected by the Syria crisis, according to the Malala Fund, and 700,000 thousand refugee children living in Jordan and Lebanon currently have no access to education.

Yousafzai's #NotLost campaign is raising money to provide learning opportunities to refugee children who have lost access to education.

"Someday, the Syrian Civil War will end," Yousafzai said in a video released by ATTN: today. "But how will Syrians rebuild their country when a whole generation has lost years of education?"

Before the civil war, most Syrian children had access to education through secondary school, and the country had a 90 percent literacy rate. Today, many of these children have been displaced from their homes, without schooling, for more than five years.

On Thursday, Yousafzai will attend the Supporting Syria conference in London and call upon world leaders to give $1.4 billion to increase education access for Syrian refugee children.

"I have met so many Syrian refugee children, they are still in my mind," Yousafzai told Reuters in an interview. "I can't forget them. The thought that they won't be able to go to school in their whole life is completely shocking and I cannot accept it."

Four years ago, Yousafzai was shot by the Taliban while riding a school bus in Pakistan. Two years later, at age 17, she became the youngest Nobel Peace Prize winner ever. She currently resides in Britain and puts much of her energy into helping Syrian refugee children get an education.
