The USA, China, France, Britain and other countries are helping Nigeria. They are looking for over 220 kidnapped schoolgirls. The Islamist group Boko Haram kidnapped them. It wants to sell them. Barack Obama said it was "heartbreaking". A top Egyptian university said harming the girls was against Islam.

Malala Yousafzai, the Pakistani schoolgirl shot by the Taliban, is shocked and sad. She said: "These girls are my sisters." She told them: "Never lose hope." She said girls also suffer in her hometown. They study and think about a bright future. Then they are kidnapped. She called this, "another kind of terrorism".
