A suicide bomber targeted an Afghan police checkpost on the outskirts of Kabul, killing one person and wounding two others on the first Friday of the fasting month of Ramadan, police said.
The attack came on the third day of the Muslim holy month in the war-torn country, where Taliban-led insurgents are fighting against the Western-backed government.
"This morning, a suicide bomber wearing a suicide vest detonated his explosives outside the city of Kabul," Kabul police chief, Mohammad Ayoub Salangi said.
"The bomber was in a passenger Toyota sedan. Police stopped the vehicle and wanted to search everyone. The bomber ran away and blew himself up. As a result of the explosion, one passenger was killed and two others wounded," Salangi said.
Kabul crime branch chief, General Mohammad Zahir, said the attack happened in Mir Bacha Kot district, on the outskirts of Kabul. Two people were wounded, he said.
There was no immediate claim of responsibility, but the Taliban last Friday vowed to increase their attacks during Ramadan. The insurgents have stepped up attacks on Afghan forces since they took responsibility for national security last month.
Some 100,000 US-led NATO troops in Afghanistan are preparing to withdraw from the country by the end of next year.
