TODAY marks the 30th commemoration of the 1994 Rwanda genocide.  Every year in April, the country enters a 100-day period of commemoration during which Rwandans reflect on historical divisions between the country's main ethnic groups - the Tutsi, Hutu and Twa.   Almost a million men, women and children, mainly ethnic Tutsis but also moderate Hutus, were killed in the 100 day murderous onslaught that saw families and friends turn against each other in one of the darkest episodes of the late 20th century. President Cyril Ramaphosa is in Rwanda for the commemoration with some suggesting he may use the opportunity to mend the frosty relations between Kigali and Pretoria. Bongiwe Zwane spoke to SABC News Foreign Editor Sophie Mokwena who is in Kigali for the commemoration
