Rwandan President Paul Kagame has been sworn in for a new seven-year term after winning a landslide vote. His opponents denounced the election as a sham. Mr. Kagame signed the oath of office in Kigali today in a public ceremony attended by a number of African heads of state. Human rights groups say, real opposition candidates were barred from running in the August 9 election, which Mr. Kagame won with 93 percent of the vote. Mr. Kagame has effectively ruled Rwanda since his Rwandan Patriotic Front ended the country’s 1994 genocide, in which Hutu extremists killed an estimated Eight lakh Tutsis and moderate Hutus.
