Kano, Shawwal 1, 1435, Jul 28, 2014, SPA -- A woman blew herself up at a petrol station in northern Nigeria on Monday, killing three people in one of three suicide bombings by females in Kano in two days, police said. The woman was in line with other women waiting to buy kerosene for cooking when she set off the bomb, AP reported. The suicide bombing was one of five attacks in Kano in two days, said police spokesman Musa Magaji Majia. Another female suicide bomber exploded her device across from a Shoprite supermarket Monday, killing herself but not injuring anyone else, said police. On Sunday, a 15-year-old girl detonated a bomb near a temporary university site, killing only herself, said Kano State Police Commissioner Aderenle Shinaba. Five others were killed in a church bombing the same day, he said, and a third bomb was discovered near a mosque but it did not explode or harm anyone. --SPA 21:56 LOCAL TIME 18:56 GMT www.spa.gov.sa/w
