I first came across Ziauddin Yousafzai when I interviewed him in 2007. He was running his own school and had set up a peace council in Pakistan's restive Swat Valley region. An eloquent English speaker, he was very keen to tell me his story on air. Our first conversation was in whispers; the Taliban had started to make inroads in the Swat Valley and were marching around the streets he told me. He was whispering as if he thought the Taliban might hear at that moment. Accolades, applause and a grim milestone Our cameras could not go into Swat so we conducted our interview on the phone. We did not use his full name or photo to protect his identity -- although Ziauddin insisted we do so. I asked him what an average day was like and he told me, "Young lady, young boys are being slaughtered here before our very eyes like goats." I was shocked by the savage image this simple statement had generated in my mind, yet this man had no fear of speaking to us.Ziauddin Yousafzai, the father of Malala, has been a huge influence on his daughterHe backed her right to education in Pakistan despite the Taliban threatMalala was shot by the Taliban after defying them with her insistence on going to schoolPakistan is a male-dominated society where women often lack the opportunities men have
