Two members of Japanese pop group AKB48 were injured on Sunday. A fan attacked them with a saw. The two singers were signing autographs for fans. They had waited for hours to see AKB48. A man suddenly rushed forward and cut them with a saw. They were lucky not to have serious injuries – just cuts on their hands and head. The attacker got past poor security. He wanted to kill anyone. He did not target members of AKB48.

AKB48 are amazingly popular in Japan and Asia. They are everywhere – on TV, radio and in advertisements. They hold the Guinness record for being the world's largest pop group. The group started in 2005 in Tokyo's Akihabara district with 48 members. There are now 140 girls. There are yearly competitions to replace older members with younger ones. There are also very strict rules. No one can date. Their contract says "love is forbidden".
