KABUL, Afghanistan — An Afghan official says a suicide bomber has killed three people including the local head of the Ministry of Haj and Religious Affairs, in eastern Nangarhar province.

Attahullah Khogyani, spokesman for the provincial governor, says another 16 people were wounded in the attack Wednesday afternoon in Jalalabad, the provincial capital.

The attacker was on foot and apparently targeted Abdul Zahir Haqqani, the local religious affairs official, Khogyani said.

Khogyani says: "The attacker who was on foot and probably waiting for his target, when Haqqani's vehicle arrived, suddenly the attacker detonated his suicide vest in front of his vehicle."

No one immediately claimed responsibility for the attack, but the Taliban and a rival Islamic State affiliate are active in Nangarhar, where they regularly attack local officials and security forces.
