Police say the Taliban safety staff was among those who were killed in an even unknown attack.
At least five people killed an explosion of the bomb, and seven of the local police reported in the northeast of Afghanistan.
The explosion occurred on Tuesday at 8:35 (04:05 GMT) near the Kabul Bank in the Kunduz Province. No group has yet taken responsibility for the explosion.
The request of the bank and four others, including civilians and members of the ruling Taliban group of Afghanistan, were among the killed, police said.
“The suicide bomber, who improvised explosive devices, detonated himself,” said Jumadin Khaxar, a spokesman for the Kunduz Province.
“The Provincial Police Command Kunduz cooperates with relevant organizations to find the perpetrators of the incident and bring them to justice,” he added.
The number of bomb explosions and suicide attacks in Afghanistan has declined significantly since the United States withdrew their forces, and the Government supported by the Taliban have been alerting in August 2021.
However, many armed groups – including ISIL (ISIS) – remain a threat.
Dozens of people were killed in suicide bombing In the Shiite Mosque in Kunduz in October 2021, and the Isil Province of Khorazan (ISKP) took responsibility.
In March last year, the suicide bomber was killed at least three people when detonated a bomb in front of the bank in the southern town of Kandahar, in an attack that claimed the ISIL regional chapter.
Despite the current attacks, the Taliban authorities say they mostly demolished the group.
