Atambaev, who took office in 2007, is barred by Kyrgyzstan's constitution from seeking a second term. Two previous presidents were driven from office by popular protests in the former Soviet republic in 2005 and 2010.

At the time of the accident, Dzhumakadyrov was reportedly traveling to the northwestern Talas region to inspect polling stations ahead of the election.
