An Afghan official says a motorcycle bomb in eastern Nangarhar province killed at least five people.
Attahullah Khogyani, spokesman for the provincial governor, says eight were wounded in Sunday's blast, which took place outside of a football stadium in the provincial capital of Jalalabad.
Khogyani says the explosion took place shortly after a pro-government rally ended at the soccer stadium.
The rally had been packed with supporters of the government.
No one immediately claimed responsibility for the bombing.
