A former Rwandan mayor suspected of involvement in the central African country's 1994 genocide has been arrested in Germany, federal prosecutors said Tuesday. The 51-year-old man, identified only by the initials O.R., was arrested in the Frankfurt area on Monday, prosecutors said in a statement. They said the man is a Hutu who served in 1994 as the mayor of a municipality in northern Rwanda and allegedly called for, led and coordinated killings of Tutsis. He is suspected of murder and genocide. In particular, he is believed to have been involved in a massacre at Nyarubuye in mid-April 1994, prosecutors said.
