Hundreds of Afghan demonstrators have flooded the streets of Kabul to protest against alleged fraud in the country's recent presidential runoff election.
Saturday's protests disrupted traffic on the major road to the airport, although the gathering was peaceful. Riot police prevented the protesters from entering the airport and stood watch in case of any violent outbursts.
Former foreign minister Abdullah Abdullah has accused electoral officials of trying to rig the presidential runoff vote in favor of his opponent, Ashraf Ghani Ahmadzai.
The United Nations assured Afghans Saturday that it is ready to assist in the presidential election if asked to help. Both Abdullah and Afghan President Hamid Karzai have urged the U.N. to step in.
Meanwhile, Afghan authorities say a suicide bomber in western Kabul killed one civilian and wounded several others, but failed to harm his target, a senior government official.
Police say the bomber detonated his vehicle early Saturday alongside the car of Mohammed Masoom Stanikzai, a senior official in the High Peace Council, a government body tasked with peace talks with the Taliban insurgency. Officials say Stanikzai was not hurt because his vehicle was heavily armored.
Witnesses say security personnel blocked off the area.
There has been no immediate claim of responsibility for the attack.
