The number of reported rapes and sexual assaults of Zimbabwean migrants to South Africa is increasing, Médecins Sans Frontières (MSF) has said. "From March 1 to May the number of cases treated was 71," MSF nurse Mashudu Nelufule said from Musina in Limpopo. Of these victims, 45 were female and 26 were male. Fifteen were children. "This is just the tip of the iceberg," said Nelufule. Many victims who were attacked had not sought treatment to prevent the contraction of HIV.
