A candidate for Afghanistan's September parliamentary elections was killed and 20 others wounded by a bomb planted in a mosque in Khost, officials said on Saturday.
Sayedullah Sayed, who also leads a small political party, was fatally wounded when a bomb detonated shortly before Friday's main prayers in the Ismail Khel of the province, provincial police chief Abdul Hakim Eshaaqzai said.
"We don't want to blame anyone for this attack as the investigation is still going on," Eshaaqzai told Reuters.
The Taliban, who frequently deny responsibility for attacks that target mosques, said the bomb could have been the work of Sayed's rivals.
The head of the provincial hospital, Amir Badshah Rahmatzai, said nearly 20 people were brought to the hospital along with Sayed, who lost both of his legs in the attack and later died.
