BEIRUT: Malala Yousafzai told world leaders they were failing Syria’s children, as the Nobel Peace Prize winner spent her 18th birthday Sunday on the Syrian border. As she became an adult, the teenager, who was shot by militants in her native Pakistan for campaigning for girls’ rights, opened a school for more than 200 Syrian girls living in refugee camps in Lebanon’s Bekaa Valley. The Malala Yousafzai All-Girls School will offer education and skills training to girls aged 14 to 18. “I am honored to mark my 18th birthday with the brave and inspiring girls of Syria,” Yousafzai said in a statement received in London. “I am here on behalf of the 28 million children who are kept from the classroom because of armed conflict. Their courage and dedication to continue their schooling in difficult conditions inspires people around the world and it is our duty to stand by them. Malala later met with Lebanese Prime Minister Tammam Salam at his home in Beirut. “Syrian children are suffering the most, being refugees for more than four years, deprived of education,” she told BBC News.
