The blast took place in Asadabad, the capital of Kunar province, and targeted the top police official in Shigal district, but also wounded 11 people.
No one claimed responsibility for the attack, but everything points to the Islamic State-Khorasan (IS-K) group, which is active in the area and has caused similar incidents in the past.
IS-K claimed responsibility for some of the most recent attacks, including a suicide bombing among worshippers last week at a Shiite mosque in Kunduz province that killed some 100 people.
Separately, a high-level delegation from Afghanistan’s acting Taliban administration will arrive in Ankara for talks with Turkish officials.
The official delegation is headed by Amir Khan Muttaqi, the acting foreign minister, who is complying with an invitation extended by Turkey’s foreign minister, Mevlut Cavusoglu.
Balkhi said the two sides will discuss how to improve bilateral relations, trade, humanitarian aid, migration and air transport issues.
This will be the first high-level contact between Turkey and the new administration in Afghanistan after the Taliban took power on Aug. 15.
The visit comes after Taliban leaders held a series of meetings this week with the United States, 10 European countries and representatives of the European Union in Doha, the capital of Qatar.
