NAIROBI, Kenya (AP) — Uhuru Kenyatta, the son of Kenya’s founding father, was named the winner of the country’s presidential election on Saturday with 50.07 percent of the vote, but his opponent refused to concede, alleging multiple failures in the election’s integrity that he said has put Kenyan democracy on trial.

Supporters of Kenyatta — a man accused by an international court of helping to orchestrate the vicious violence that marred the nation’s last vote — flooded the streets, celebrating in a parade of red, his campaign’s color.
