Seven non-governmental organisations (NGOs) in Tanzania have formed a coalition to fight female genital mutilation (FGM), a practice that is still widespread in the East African country. "Various studies have shown that at least 18 percent of women in Tanzania are victims of FGM," Hellen Kijo-Bisimba, the coalition's co-ordinator, said in Dar es Salaam on Friday, ahead of its official launch on 6 February.
