NAIROBI, Kenya Sister Leonella, a nun who devoted her life to helping the sick in volatile regions of Africa, used to joke that there was a bullet with her name engraved on it in Somalia. When the bullet came, she used her last breaths to forgive those responsible. "I forgive, I forgive," she whispered in her native Italian just before she died, the Rev. Maloba Wesonga told The Associated Press at the nun's memorial mass in the Kenyan capital, Nairobi, on Monday.
