Abuja - Nigeria's president Goodluck Jonathan is urging his nation to vote peacefully and accept results of Saturday's presidential election, which analysts say will be the tightest in the nation's history.
Jonathan said in a televised broadcast on Friday that no political ambition can justify shedding blood. Dozens of people already have been killed.
Jonathan and leading rival Muhammadu Buhari signed peace pledges on Thursday and urged their supporters to avoid violence.
