The attackers came into the village at night wielding machetes. Not even two-year-old Rachele-Ngabausi was spared their violence. The last thing her 11-year-old sister Mave Grace saw before falling unconscious was men with machetes cutting open their pregnant motherÕs belly and killing the unborn child. When Grace woke she was surrounded by dead bodies. Her left hand was cut off just above the wrist. ÒAround us we saw corpses everywhere,Ó Mave Grace says. Wearing a green patterned dress, she squints into the sun as she holds up her handless arm, the scabs of the stump still not fully healed. Mave GraceÕs home village of Tchee lies in the eastern Ituri region, where ethnic strife between Hema herders and Lendu farmers has cost untold lives and forced tens of thousands to flee since it started earlier this year.
