Killing eight civilians in an area largely inhabited by Afghanistan's minority Shiite Muslim community, a bomb attached to a handcart exploded in Kabul on Friday.
Injuring 18 people, the blast took place when Shiites in Afghanistan are commemorating the first 10 days of the Muslim holy month of Muharram.
According to police spokesman Khalid Zadran, "Security teams are trying to find the perpetrators."
Saying the bombing was the "work of those who are enemies of Islam and the country", government spokesman Zabihullah Mujahid confirmed the toll.
