The bomber struck shortly after noon in front of a car carrying Taliban police chief in eastern Afghanistan, killing 11 people and injuring 11 others, officials said.
The blast occurred in Asadabad, the provincial capital of Kunar, targeting a Taliban police chief in Shigal district, an official from an Islamic group said.
“The police chief died and eleven people were injured,” he told AFP on condition of anonymity.
A doctor at Kunar General Hospital confirmed to AFP that he had received 11 casualties, including four Taliban fighters and seven civilians.
No one has claimed responsibility for the attack, but the Islamic State-Khorasan group, operating in eastern Afghanistan, has claimed responsibility for a similar attack on the Taliban in the past.
The Taliban have been fighting IS-K since its rise in Afghanistan in 2014.
IS-K has claimed responsibility for some of the latest attacks, including a bomb attack on worshipers last week at a Shia mosque in Kunduz province that killed at least 100 people dead.
